Sorc Healer here from the stat of the game, War Hero title, war hero gear, rank 75 doing warzone and not Ilum because i hated it.
I did level 50 pvping, and i can say to you healing it's very bad now with 1.2.
I have 1200 expertise and in my server full populated, i die in 3-4 sec sometimes vs Dps with my same gear.
It's not about the healing output or TRauma debuff, it's about the imba dmg now dps can output.
