I'd love to see a British Class, but he seems a bit OP. His rifle would make him deadly at long AND close range assuming that your aim doesn't suck. Not to mention he has a shotgun AND he doesn't even have to switch out his melee weapon...
I'd like to see:
The Rocketeer.
Health: 175
Speed: 80%
Role: Support
Weapons: Shotgun, Akimbo Pistols, Swiss Army Knife.
He'd also have a Jet-pack, but it would work in a similar fashion to the Spy's Invisibility Watch or the fuel on the Pyro's Flamethrower so he won't be able to terrorize the sky for too long.
Character Info:
Nationality: Canadian/US
Probably OP, but an interesting thought, eh?
And nice drawing, by the way.
