In the Deckard Cain Meta Tier List made by @Oxygen, @MagikMurlok asked if someone could compile a list of Heroes that have strong self-sustain that can be viable in matches that features no Supports. I decided to help.
I ended making a list of all non-Healer Heroes that have any form of self-healing. Took me around 6 hours to compile every single nook and cranny (with all the revisions and edits), so here it is! I hope this help. Any feedback is welcome.
I've also included a suggested build for each character to use in the event that there is no Healer in the team, aimed at maximizing survivability.
Special thanks to @ExorionAether for the help with talents and Heroes I missed, forgot or did not include originally for other reasons.

TOP 10 BEST PUBSTOMPERS WITHOUT HEALER
Deathwing: since he cannot be targeted by buffs and heals from his allies nor debuffs from his enemies, Deathwing is a powerful candidate for teams without healers. All his level 1 talents are aimed at self sustain, and he also has some few other defensive talents; while you'll be sacrificing damage for survivability, Deathwing will still pack a punch. Fenix: as long his Shield doesn't drop completely, he has one of the most powerful lane presences in the game, essentially having two healthbars. And if losing his Shields he can simply retreat and let them replenish again. Just be careful with hard engages, stuns and damage-over-time (as each tick will put Shield Capacitor on cooldown). Malthael: ridiculous sustain that allows him to 1v2 or even 1v3 under the right circumstances. Make sure to hit as many opponents as possible with Basic Attacks to maximize his sustain. Dehaka: incredibly sticky and slippery, with a global presence that allows him to engage and disengage at ease. His trait combined with Adaptation makes him really hard to kill. Blaze: powerful lane presence and one of the best self-sustains in the entire game. Diablo: his recent rework made him absurdly resilient, with a self-sustain that can surpass Blaze's under the right circumstances. Sonya: still one of the strongest solo laners in the game, with reliable self-sustain, great damage overall, and strong engage potential. Medivh: with a very versatile kit, he can provide damage, mobility, vision, crowd-control and most importantly, damage immunity and healing. ANY team without a Healer greatly benefits from Medivh. Yrel: the only non-Healer in the game that can directly heal other characters with Gift of the Naaru and Word of Glory, making her a powerful emergency off-healer. ANY team without a Healer greatly benefits from Yrel, assuming she picks those aforementioned talents. Thrall: very strong on really long matches, as his most powerful quest talents require a lot of farming. At the endgame he deal eye-watering damage while healing for huge chunks of health. THE TOP 5 BEST SELF-SUSTAIN TEAM COMBINATIONS
Deathwing, Medivh, Stitches, Kel'Thuzad, Kael'thas. Deathwing, Medivh, Garrosh, The Butcher, Kel'Thuzad. Deathwing, Medivh, ETC, Fenix, Kel'Thuzad. Deathwing, Medivh, Johanna, Cassia, Fenix. Deathwing, Medivh, Yrel, Raynor, Thrall.

I've been a Healer main since I started playing this game, and Auriel is one of my favorites. Even though we have Deckard, Ana, Anduin and other powerful Heroes in this class, I still consider Auriel one of the best Healers in the game given her very strong lane presence given the fact she doesn't use mana as resource, therefore being able to stay in battle as long she has someone to provide energy through her trait, Bestow Hope. Also, the fact she can endlessly increase her own energy with Reservoir of Hope can potentially turn her into the strongest healer in the game, in terms of raw healing output.
Ever since her launch, I have been testing Auriel's energy generation with a huge batch of heroes. In general, Ranged Assassins are often the best candidates. With that in mind, I decided to compile a list with the Top "Hope Bearers" in the game to give her that sweet energy.
_________________________________________________________________
This guide will be updated constantly as new Heroes are launched and/or existing Heroes are reworked in a way that affects their DPS.
This is the build I currently use, by the way.
Cho'gall: the uncontested champions to provide energy to Auriel. They are a huge lane presence, combined with 8 skills in total makes them a fantastic pair with Auriel to generate energy in double. While they lack the burst of other heroes, they will be constantly dealing damage thanks to their low cooldowns and combined abilities, which will translate in energy really fast. The Cho'gall + Auriel is often a powerful combo even in rankeds, although rarely picked. Lunara: a skillful Lunara player will know how to spread her poison among various targets, giving Auriel a healthy sustain in energy, becoming much stronger at later levels. Raynor: even after his nerfs, he still is one of the best Heroes in the game for sustained damage and situational burst, which translates into energy for Auriel really fast.  Fenix: high sustained damage and exceptional poke makes Fenix a really good hope bearer, specially since his high self sustain through his shields allows Auriel to focus her heals on other allies. Valla: a combination of high burst damage and sustained damage, which makes her a fantastic source of energy, regardless of her build. Tassadar: the recent rework turned him into a powerhouse, with massive burst damage. A single Shock Ray that hits an enemy can fill over half of Auriel's energy gauge, and that's without the quest talent. In addition, with Force Wall being baseline now, he can create obstacles that Auriel can use to stun her enemies with Detainment Strike. Kael'thas: high AoE burst. Living Bomb is specially powerful since it can easily spread to other targets in chains. Phoenix is specially useful to generate energy as well when defending objectives. Sylvanas: given the right circumstances she can surpass Lunara in energy generation, if she follows the Shadow Dagger build and gets enough stacks. Gul'dan: combines the best of both worlds: spike damage and damage over time. The low cooldown on Fel Flame makes him a giving constant damage in the form of energy. The damage over time from Corruption is decent to generate hope, but only if it hits multiple targets. Cassia: much like Valla, she has a bit of everything: burst and sustained damage. If she hits at least two blinded enemies with Fend your energy will skyrocket. While the recent rework nerfed her damage in the early game, she can more consistently provide energy in the late game. Hanzo: long range poke that makes him pretty reliable for getting energy from afar. In specific maps his Scatter Arrow is insane for energy generation. Chromie: huge damage spikes with her skillshots. A Chromie with good aim for Sand Blast will fill the gauge really fast. Dragon's Breath is absolutely fantastic as well and will often max the gauge in one go if used on a crowd of Heroes + minions/structures. Sgt. Hammer: while in Siege Mode she can generate huge amounts of energy if positioned correctly. Auriel can also stay near to peel for Hammer with Detainment Strike if needed. Alarak: can potentially become the one of the strongest candidates for Bestow Hope if he manages to get over 150 stacks of Sadism. Other than that, he is pretty solid with a point-and-click poke in the form of Lightning Surge (specially if related talents are picked) and high burst with Discord Strike. Mephisto: very high AoE sustained damage. Lightning Nova can fill the energy really fast if it hits at least two heroes. Consume Souls is fantastic because it provides a global source of energy. Kel'Thuzad: potential for overflowing energy thanks to his eye-watering combos. However, this reliance makes hard to keep her trait on him all the time since he is very cooldown reliant. Orphea: in a similar fashion to Kel'Thuzad, she relies a bit too much into landing her combos to provide consistent energy, but it is still very reliable and above average. Zagara: can provide fantastic pressure with her basic attacks and abilities, with a lot of sustained damage that will rapidly fill energy for Auriel. Since she will most of the time have a Roachling or Hunter out, this translates into more damage. Zarya: her synergy with Auriel is fantastic since neither use Mana as resource, meaning less needs to visit the Healing Well. Zarya's piercing splash damage from her basic attacks also results in constant amounts of small energy that holds really well. Jaina: her potential rivals Kael'thas, with a very strong burst potential. However, this is gated by her very high cooldowns and over-reliance on the rest of the team to setup ideal situations for her damage to flow. However, if you notice your Jaina pops Icy Veins and either of her Heroic Abilities during a teamfight, swap your Bestow Hope for her.  Ragnaros: very high burst damage, although he needs to be in range to do so. However, he can be affected by Auriel's trait even while under his Molten Core. Nazeebo: I absolutely love pairing with Nazeebo for the simple fact he can make Zombie Walls every 14 secs, which is great to stun opponents with Detainment Strike. However, both his meta builds can grant a lot of energy. Malthael: provides a very large sustained damage through his trait. Not as good as Lunara's, though. Zul'jin: potentially the best energy generator for Auriel in the entire game due his Twin Cleaves (specially if talented into) and high damage from basic attacks. However, he is ranked so low because he can only be this fantastic hope bearer once he completes his "You Want Axe?" quest, which is usually late in the game. Qhira: combines damage-over-time with burst, in a similar vein to Gul'dan, being capable of giving consistent damage. The only thing that gates her from being higher is her reliance on Basic Attacks, meaning she won't always give consistent energy; but will do so in long teamfights. Azmodan: massive burst damage once he completes his quest. Ranked so low for similar reasons to Zul'jin. He is also very cooldown dependent (more than Kel'Thuzad), meaning he is unable to contribute with energy at regular basis. However, should you notice he is about to use his globe, put the trait on him. The Butcher: once he completes the Fresh Meat quest, he deals insane amounts of damage fills up the energy with two or three basic attacks. However, since a good Butcher will not engage recklessly, he will only generate energy reliably during Team Battles and skirmishes.

I recommend everyone checking his channel. He does tons of video guides and analysis.
 

Hey guys with the newest heroes of the storm patch out, there were a ton of changes and it's easy to miss something. I go through ALL the changes this patch brought in the video below. I hope you check it out and find it helpful.
 
 
 

Out of boredom during long work shifts, I came with this idea to allow players to come up with their own concepts.
In this thread you'll be free to create your own ideas of Heroes, Maps and skins. Shower thoughts are always nice, and I'd like to see your ideas. Plus, who knows, maybe we can send this to Blizzard and light some bulbs.
Allow me to start with my idea for a Hero I've been wanting to see for a long time:
