I hope its like that or close to that
, but a team fortress approach? Where you pick a very very specific class that you have to play in the way they want you to or extremely close to it? With your ingenuity severly limited by the defining lines of a class? Where you can only use weapons designated for that class and no others? Where you can change classes after you die? Those are just some things that im not fond of in the tfc class system even though its a great game.
If i could pick a approach from another game though i would hope for firearms approach but much, much more advanced.
