Thrown TNT from the old trailers for the demoman that would replace the stickybombs. He'd get two or three tops. That could be thrown into a highly saturated area either heavily damaging or destroying most things in the area. Ideally it would be just enough to kill a level 2 sentry if absolutely right next to it. It also would have about four seconds until detonation after being thrown to make sure it wouldn't be used as a primary weapon against people.
Pyro to have a sort of "flame shot" from Metal Slug. You would effectively call it a fire shotgun but with a tad difference. It would burn enemies but for a significantly shorter period of time (15-20HP rather than 50HP for the flamethrower). Secondly the shot would be considerably slower than your regular shotgun, twice as slow. Finally the range wouldn't be forever, it would stop in about two seconds to secure Pyro as a close quarter class.
