They are
fragile, masochistic, annoying with certain abilities(especially the wererat's knockback). It is tough keeping them alive sometimes simply because they draw too much aggro on themselves. Give them defensive abilites or something. Make them partial augmentation like the cat. Give them abilities to CC adds. Just please make them overall a little more useful instead of dying 10 seconds into a boss fight.

They can't regen from 0 HP.
devs should have made them all invulnerable to begin with.
make them die when the player dies.
only thing remotely worth getting is ioun stones or cat.
anything else dies 10 seconds into a bossfight and is totally worthless to the team. but no big deal anyway because they don't contribute much anyway.
