Healers need an overhaul

[Tychonius]

There's only so much support you can provide to people in any situation. If party members keep dying, and the answer is "you better keep their HP at max OR ELSE" then fine; but if party members keep dying, for FFXIV, the answer really is "get good," per Yoshi P once upon a time, because there aren't many encounters where players should be dying over and over unless they're actively doing something wrong (such as standing in the wrong place at the wrong time).

Yea, that's my original point. The thing that makes parties fail tends to be errors in dealing with mechanics, not simply "the healer isn't good enough", because it would be too binary if everything hinged on whether or not the healer can keep up.
