Hello! I am Syanah. :) 
Anyway onto the details. I'm at 904 equipped currently. My weapon is at 919 with two of the ones that makes Living Seed do more healing, and the one that increases mana regeneration. As of writing this I have 48 traits. My talents are Cenarion Ward, Displacer, Guardian Affinity, Typhoon, Cultivation, Germination, and Flourish. My haste is at 26%, my crit is at 17%, mastery at 11%, and (somehow even though I just kinda ignore it) versatility at 12%. 
Ok. My rotation for large amounts of burst is normally wild growth, swiftmend the lowest, cenarion ward on the next lowest, then throwing rejuvs as much as i can before florishing.
My tank rotation is just keep as many hots on them as i can, use Ironbark when it's off and when they need it a lot, and keep Cenarion on the tank taking the most damage.
For large damage on people i immediately hit Ironbark, regrowth to stabilise if it's very bad, then other hots to get a better Swiftmend. 
For my mana issues I first like to use what I call "manaburst". It's pretty much just a macro binding Innervate and Essence of G'hanir to work together. I also have Leytorrent potions. 
For legendaries I currently use Essence of Infusion and Velen's Future Sight. I have The Dark Titans Advice, Pyrdaz, and X'oni's Caress. Trinkets I have Ephemeral Paradox, Etraeus' Celestial Map, and the Flask of Solemn night. I use Solemn night and Velen's.  I have my four piece in the form of cape, head, pants, and shoulders. 
Soooo.. pretty much it'd seem like I'd be doing ok but honestly I feel like I don't do enough. (These aren't 100% accurate numbers, so be warned.) I usually seem to be around 400-600k, but it drops to mostly 200-400k at the end of fights. I raid in a heroic guild, so it's a little less important that I be the very elite of the elite, but still. There's 3 healers in all. Myself, another Resto, and a Holy priest. We have another healer, a resto shaman, who doesn't heal all that much anymore but still. Pretty much I'm always behind them the holy and the other resto. (They are really good though, so /shrug)
Anyway I'm going to post my armory, and warcraftlogs. (I have no idea how to use logs so... here goes!) 
Armory:

 https://www.warcraftlogs.com/rankings/character/13553554/11#difficulty=4&class=Druid&spec=Restoration&metric=hps&bracket=21
 
I think I got it to show my healing from on of our runs... I think. 
https://www.warcraftlogs.com/reports/xfKndz9P2hgHLbV3#fight=7&type=healing
This is the most recent I can find. 
So basically I just wanna know from some other restos how it looks, how to improve, and what I should look to do. Been worried that my healing isn't up to par with what a 904 should be so that's what mostly made me post this and because I wanna be the best i can be for my guild and our progression for Tomb. :)
(Also I apologize if I this wrong. I have no idea what I'm doing.)
