Can Healer Balance Survive a 4th Healer?

[Mimilu]

"You need a shield to live" doesn't suddenly make healing exciting, which is why the pure/shield divide seems to be going down the wrong track. It just adds a bland necessity that restricts job comps a bit.

For me, I think the pure vs shield dichotomy is kind of too shallow to really allow for more interesting healers.
Instead, I think they could go further/more general and split healers into Proactive vs Reactive.
Proactive healers would set things up before damage is done (shields, damage down buffs/debuffs, heal bombs) while Reactive would heal after damage is done (burst heals, regens, drain heals).
This would at least give them more things they could design a healer around other then if it can place shields or has higher burst and/or regens. :B
