I always felt like fixing healers should be simple: more consistent party wide damage, faster auto attacks on bosses, more use of the infirmary debuff( not removeable, reduces hp recovered) The problem is they probably don't want to do this because if the actual healing portion of the job is hard then less people will play the role, because lets be honest at this point in the game doing the base level healing is pretty brain dead(imo it's been pretty brain dead since HW came out).
