I would not be surprised at all if the Devs decide to disable Cleric Stance in dungeons/trials like they did in PvP.

They made it clear that they don't want healers to dps too much with decreasing Holy's potency by 10% per use up to 50% and that's the same with ASTs Gravity. Then there's not adding any ACC to healer's gear.

With them getting rid of accuracy in 4.0, the only thing left will then get rid of CS. Even if CS is gone, people will still want healers to dps
