Drawing a sane conclusion from your weird idea: It would be really awesome if it cast a Confusion-type effect so that PvE enemies would attack each other instead of you. (So, it's like they decided they liked you, thus Cupid... see, it was related.) It would have to be an option on the tree, since that would be beyond useless in PvP. Unless it actually made blues turn red and reds turn blue, and switched the ability to damage them.. So, only team kills... But, I imagine the coding for that would be difficult, and once it was known, people would just know they had to wait it out.
