Given their trouble with AST balance in the past, the Regen and Barrier healer idea is something that SE had no choice but to go to. They're the ones who put themselves into this corner, and they have nothing but to themselves to blame for it. These next few months are going to be crucial as healer gameplay will be put into question. Will this separation of healers help SE design better gameplay for the four jobs in general or will it get worse? I can't image it'd get any worse for healers than it is now. But anything is possible, and we're not off to a pleasant start.
