Healing in XIV is pretty much a fake role that could be nigh effortlessly replaced with a handful of role actions and buffing personals.
In doing so, the game would likely become more accessible and have more depth, so not only is the healing role phony the mere presence of it is possibly a detriment.
This is the only MMO I've ever played that I don't main healer in. It is the single worst part of this game and it borders on the incredulous how the developers are OK with slop design like this.
I wouldn't be shocked if a segment of the community turned on the game a bit if 7.0 doesn't at least try to move a few mountains. I love the thing but at some point the sweeping of huge and obvious problems gets tiring.
