I dont like the idea of a spy stunning, the whole purpose of a spy is to get in and out...stunning the enemy imo would be of no use. We already have a class for bomb type weapons, dont need another. Throwing knives....its ok, but i dont think it would insta kill anyone..it should be a replacement for the gun imo. What the spy needs imo is a better sapper, at the moment its way to easy to knock off. Would love the ability to walk through the enemy or a cloak stab, LOL that would be way to OP. Nothing we think of or that valve comes out with will be balanced and everyone, and trust me everyone will be complaining about what ever weapon they come out with.
