30% hp loss to do the same dps as other specs is a terrible change. Please reconsider this heavy nerf.
Or, better yet, just buff fire pvp damage on core abilities like pyroblast and phoenix flames and scrap this awful talent.
It’s fine in some battleground / group content where you have several healers, frontlines, and peelers to keep you safe in the backline, but fire has 0 chance in the majority of arena content, especially 2v2.
