We have four healers. They already separated into regen/shields so why not do the same with dps/support. Whm/Sage should have more dps abilities to fill those who want to dps more while Ast/Sch should be the healers that lack the dps rotations but offer more support to the group as a whole.

So you can have a choice. All healers will still be viable in all content but it will kill these kinds threads about some people wanting more dps abilities while others wanting more support abilities.
