I'd definitely like to see AST nerfed because it's borderline godlike (does better on everything than a WhM, including damage, I've seen AST damage boards going over everybody but the big hitters like GNB/SMN/MCH), but I still do feel that regen healers pose a real problem to the game. Whether we consider that the game is actually meta balanced around healers being here to do what they allow, or that the game is balanced around no regen healers being here, the real problem is that a team without one is worse off than a team with one, whether it's an AST or not.

They're frankly cancer, and if people drop too fast in crystal rank and LPs, then perhaps it's a problem of design rather than requiring healers to save people from dying before they even press purify.

Also I'm sorry but a single CD for Cure II/III is nothing. We're not in pve where missing a cast is a huge deal either, especially when your replacement cast is saving your team from getting kill staggered.
