A recurring frustration with my paladin, but really with any character with a self-heal spell, is that when fighting undead mobs, if that enemy is the current target, the spell deals damage to it instead of healing my character.
I know, I just need to target my character, but...
Maybe there could be a toggle, stance, UI check box or something, that will auto-target the player character when fighting undead mobs just as when fighting other mobs.
I am not sure what the work around would be when a player wants to do damage to the mob and not actually heal, except to turn off the feature, but I bet someone could come up with a better idea.
