To be serious, if FFXIV goes the way other MMOs have gone with damage mitigation healers, SCH will eventually become the king of all the healers. They'll try to balance them with the others. Every new expac will give them nerfs but the nature of their class is such that nerfs make them barely playable and they will soon get buffs again.

Look at WoW. They've been trying to nerf Disc Priests for whole expacs and nothing having. Atonement healing didn't help things (damage done by the priest would smart heal lowest HP player within a radius with 90% of damage done) but they were beast before that and they're still beast after that.

I really hope SCH's don't go that way so much.
