I'm 100% on board with this. Healers should be the buffers/debuffers of FFXIV.
Apocastatis (sp)? Should be a role action for healers and renamed Shell. Buffs the group to take reduced spell damage.
Put Protect back in like pvp action. Buffs the target to take reduced damage for a short time.
Feint? Give it to healers as a mob damage debuff.
