How useful is grease. I've found several uses for it so far, but many people always tell me it sucks.
I don't see how it could suck so much if you can keep an few enemies at the bottom of stairs and in your fire wall, or Make them slide off a mountain.
On top of that, you can use it on players that tick you off. So why is it so bad? Can it not be heightened or something? Or do people dislike sliding that much?
