I havent played 2fort or TF2 consistently in years but man, I really really really have always wanted some things to expand his play style. And fuck. They actually listened.
I've always wanted something that made Pyro good at defending. >Gas can
Imagine a pyro using this shit all over a point or sentry nest, detecting spies with the fumes. Or detect disguised spies that actively avoid it, etc.

Can potentially reach areas an offensive class SHOULD be able to reach
The fireball blaster sounds cool, if it has unlimited range. Maybe a...heavy duty flare gun? The Hot hand though sounds like another shitty meme melee weapon nobody will use, but the other stuff sounds great and fun.
The 2nd banana also sounds good, if it recharges fast, it could be a nice medic healing tool for heavies, if they can throw it and force bananas down their medics face.
