Why were healers "nerfed" in last update?

[CryBloodwing]

So people say in SB content, healing is hard and there are a lot of healing checks.

So, why did the make WHM Regen cost more mana and Scholar Chain Stratagem have less time?

Seems to me like healers get the most "hate." We get blamed all the time for stuff. Loot rarely drops for us in things like raids. Now our skills get worst when it was already hard?

While I know these two changes are not too big, they still do show that healers got slightly nerfed.

We also need to add vitality for some high level raids simply because our HP is not high enough. Less room for piety and other melds. I think maybe the HP on healers should be increased because of this. Like how much HP added per level. Other roles only have to really add what is needed for their class, like crit rates/direct hits.
