I like the create-a-class idea. Frontlines was a nice game that went unwanted by many gamers though(too bad... I loved it). It could work a little like COD4's class system which was one of the best ever made. But of course some would hate it because it is not the classic battlefront style.
You are right about that if the 10 classes were balanced, it would still work but not the ones that omg...whatever his name is... made.
