I have a headcanon that the destroyer life classes can heal, but since they are destroying through life to do so it leaves their friends with insecurities, low self-esteem, etc and everyone is pissed at them but the prince/bard Is just like "but your not dead so stop complaining"

I feel that works well, there’s also such a thing as ‘overhealing’, I’ve stated before that a Maid of Life could improve the rate at which your cells duplicate and heal to the point of giving you cancer, so some kind of thing like that could be plausible for a Bard/Prince as well, I’d say.
