MAYBE the PoM changes are a bit drastic, but I feel like what you propose doesn't change the fact that WHM doesn't really have much oGCD healing abilities and is the only healer that really has to interrupt their DPS to do proper healing. Not just that, but with Assize being tied to your DPS, hardly ever is it used for healing except by coincidence or if you co-ordinate with your co-healer, so one of WHM's healing oGCD's usually goes down the damage drain leaving you with just Asylum and Bell for non-GCD healing. All i'm saying is if they're gonna give Sage 6 oGCD AoE healing abilities, AST 5(arguably 6 if you include Microcosmos) and SCH 6, they could at least bump WHM up from 3, especially since A.) Assize is tied to damage, B.) Asylum is a bubble and sometimes isn't nearly bursty or wide enough to cover everyone and C.) Bell requires you to be hit to activate or get healed for about half of what the total potency of bell is supposed to do.
