Can we just STOP this? Balance isn't only relevant to progression raiding, or world first raiding or whatever you want to say. The only content it truly doesn't matter in is dungeon content. Ex trials and on, IT MATTERS. There's a huge disparity between the healers, and it shouldn't be ignored just because you can suck it up and handicap your party if it came down to it.
Sooner or later, WHMs are going to be locked out of PFs like AST was.
