Well, I also have no problem with a full ground-up rework of healers, honestly. I just don't think it's terrible the way it is, either.

To put my feelings on the matter into a very short form:

I want healer DPS to remain simple (some change is fine, but no complex rotations please).

I want oGCD usage to still be relevant, but have the damage threat amped up to require actual GCD healing (so we agree 50-50 sounds good to me).

And I want healers to have unique identities which aren't hampered by a pointless attempt to balance everything perfectly.
