The thing is, the game kind of splits what would be traditionally thought of as "psychic abilities" into the illusion set, (creating false images, causing false wounds, etc), and mind control, (psychokinesis, hypnosis, etc). What they could have done was to have mass confusion despawn the affected enemies and replace them with "pet copies" under your control, (thereby eliminating the XP penalty and such), or maybe just change them to now be flagged as allies...
