It can also be abused (much like concussion blobs, secondary grenades or simple melee kicks) to get you sniped, heavily shot or sabered without any repercussions... what's one more hole in the TK system?
(On the other hand, this one probably also means that you don't get credit for tossing
enemies off a ledge. Seeing as that means it's a more universal issue rather than
just a hole, it might still be fixable.)
