I am mainly talking about heal firebrand.
When I first joined this game, I ask people which class should I play?
They say: you can try any profession you like, because due to build system, almost every class can heal/dps/support.
But then after reaching the end game I find it is not the case.
Heal Firebrand is the only wanted healer in fractal cms/T4. I played multiple healing spec (druid, hb, tempest). And by comparison HB is allowed to do way too much.
It can give all 12 boons except alacrity. (If you don't count condition->boon conversion)
Due to prevalence of consecutive CC from mobs, stability is very important. However, only HB here can give multiple stacks of stability, and more than one skill can do this!
Moreover, it can give a lot, a lot of aegis, which simply negates many mechanics for other players.
It is also the only spec among these healers that can give quickness. How is this fair to other healing spec?
