Many in the game who really are not good generally have "life bar anxiety". So they come up with weird stuff like always being at 70% or even 90% HP+ non-sense when the mechanics don't dictate it. These include those weird clemency tanks who won't use holy circle on mobs. Cause that's the best mitigation in the game, when something dies faster.

It's worse when the anxiety is a healer because they keep you topped up so much that they overheal like mad, and don't trust things like Asylum when that's well over a 900+ potency heal and still pop a medica 2 for some unknown reason. Next thing they realize they are out of MP for some reason, cause of overheal.
