Pretty much what most rbg leaders say is the same thing the above poster mentioned. Survivability, and mana problems. I do premade cta alot instead of rbgs, just dont care to do rbgs at all, its pretty much the same thing when there's a disc priest waiting to get in they won't be picked over hpal/rsham/rdruid..
Im not going to lie to you, you're going to have to get your resilience up to over 9k if you want to see a difference in your survivability, because our survivability does suck aside from our mana problems and you're around 5k.
Disc priests are always the first target to explode when it comes to premades so stack that resilience up as high as you can. You can't bubble/cc like a pally, you dont have escape mechanics/cc and survivability talents a druid has, you dont have the utility and survivability a resto shaman has, you dont have the mana bar of any of those classes have and you dont have any insta cast big heals you can drop a la natures/ancestrial swiftness, etc, so..
What you bring to the table is mass/offensive dispels, a situational leap of faith, shields and a fear that you have to run into melee range to pop, or a root if you spec for it, or a single target psyfiend fear, but that thing loves to target hunter and warlock pets over human players in bgs. Would have been nice if we could get both psyfiend and void tendrils for some more utility..it hurts that void tendrils/psyfiend and mind control are all of the same tier of talents..would be neat if they could swap one of those talents out with another skill on another tier like our lvl 75, or even last tier. Our last tier is nothing to write home about honestly compared to other classes last tiers...nothing that makes me say "wow" like when my warrior used to be my main and I saw avatar.
