I disagree with everything said in the thread. I better ban you all.

Everything balances each other out.

Sniper nest? Burn it out or drop a bunker buster on it.
Machine guns fucking your shit up? Go Saving Private Ryan on it and snipe that shit and burn any survivors
Pesky flamethrower? Snipe it, or if you're feeling ridiculous, drop a mortar on it.
Shotguns? Shotgun them back.

Everything gets balanced out.

How is sprinting even possible? since most of the time you have to jump
What would be good is better jumping as right now its a pain
As for tunnels they already have a speed advantage
What this game really needs is some kind of artillery or more explosives
