Spy all the way. I used to be good with the old tfc spy but now… I can truly cloak… It is amazing at how easy people can be to kill.
I would prefer friendly fire on though :\, or some kind of penalty for shooting your own team for no reason. It would be great to actually feel like a spy! I rarely run around in the enemy base uncloaked because 99% of the time they will shoot me 3 good times ‘just to check.’
At any rate, still love the spy ^^.
Beyond that I like all the other classes equally. Everything is amazing to play. (I do wish the sniper had a mine or something he could lay down).
