This is why I think it would be funny, actually. If the backfire result were potent enough, you could see people popping enfeebling items like crack to get a backfire on them. I mean if you could backfire silence into MAB, wouldn't you be using silencing potion to backfire yourself all the time? Unless backfire were a spell instead of a JA, of course, in which case silencing yourself to use it would be as dumb as the mobs that still cast silena on themselves...
