* Try to make bots compatible with flying.
* Assassins should become invisible in dark areas, and should insta-kill anyone from behind.
* It'd be nice if super-jump didn't jump where you are looking, but instead just an over powered jump.
* Possibly add web-slinging? You could make it like the grappling hook, but look like web, and not as strong of a pull. A spiderman class could have that, and walking on walls.
* Steel skin power, you use it and it covers your skin in steel, making you take half the damage of everything, and making you bullet-proof. After it wears off, you can't use it for a few minutes.
* You could have a no-clip type power, like Kitty off of X-men. It'd be tricky to only make it go through certain things, though, so I doubt this will happen.
That's all I have for now. Extremely awesome mod, keep up the good work!
