I'm making a survival build for guardian druid for dungeons, lfr and a bit of battleground. I have Soul of the Archdruid and Dual Determination. Now I got Cinidaria, the Symbiote. Should I choose it over my existing two?

I have a question for Arcane mages that I couldn't find existing guides mention on any website. In dungeons, mana is not typically an issue as a healer because you can just drink/eat in between packs, I mained a healer up until now so that mindset is just ingrained in me. As Arcane Mage, would the same principle apply? Is it optimal to just forgo the conserve part of the rotation and just burn as much as you sustainably can with every  pack, since you can just eat conjured food in between packs, or should you still do conserve/burn phases similar to what you'd do in a raid?
Thanks.

hello, so i am following this deck - https://www.icy-veins.com/hearthstone/elemental-mage-deck and i was wondering which card i should buy next and i dont have much dust left. I need the following cards
Primordial Glyph x2
Pyros x1
Arcane Keysmith x2
Blazecaller x2
Frost Lich Jaina x1
 
I have 1945 dust left with the option to disenchant "Archmage Arugal" with a total of 2345, because i dont use it, nor do i know if its any good?
 
 
I can either go with x2 Primordial as the guide says this is needed for the deck + x2 Blazecaller for late and x1 Arcane Keysmith? but then  i wont have the pyros for early or Jaina for late.
 
Or i can go balls out buying x1 Frost lich jaina and x1 primordial glyph ? / Or just Pyros and x1 Primordial. I dont know.
 
My last scenario is buying Frost lich jaina and x1 primordial by selling some rare cards, then use "Archmage Arugal" instead of Pyros for the time being and combo it up with AI for 2 extra cards, and hope its something good.
 
 
 
any help is grately appreciated.

About Us
Skunkworks is a guild for players who can not or do not want to commit to the time-intensive raid schedules of traditional "hardcore" guilds.
However, we still maintain a high caliber player environment and make an efficient use of our raiding time.
We raid Tuesdays and Thursdays from 7:00 - 11:00 PST, just 8 hours a week and never more.
 
We are very protective of our guild environment and selective in recruitment. We are looking for solid players mechanically as well as intellectually.
We all get paid to deal with idiots, why should we pay to spend our leisure time with them as well?
 
Skunkworks has been around for multiple expansions and has historically always been at the top of the 2-night raiding guild scene.

As a retribution Pally should I equip the Insignia of the Grand Army instead of either Soul of the Highlord or Chain of Thrayn.  Could not find in the icy-veins guide about this ring.
Thanks
