Healing is more than "Whos got A Regen/Shield/Buff" etc. Its also a matter of how those heals are delivered. Otherwise were essentially saying every single DPS job is just a straight up carbon copy of one another because they all predominately just do damage by using skills.

If youre gonna see another healer, itll probably be a hybrid healer, and will probably incorporate a system we havent seen yet. My personal thoughts would be a chemist equivilant, with a system of stocking heals as an expendable resource. That is you pre-create a bunch of heals and hold onto them and throw them out when needed. It may end up being a strong burst healer. Dunno how this would work out in the bigger picture but it might be interesting.
