But it's important to make a distinction between what's an attack or not. "Doing something bad" to someone is not necessarily an attack and the mechanical distinction is there for good reason. Mirror Image doesn't protect you from save-based spells or effects, for instance; only attacks. It's not intended to be that powerful.
Normal invisibility is not supposed to be that powerful either. There is improved invisibility for a reason.
