6. "Pick 10"
Pick 10 is a new class system for Black Ops 2, which allows players to pick 10 elements of their class; there are ten slots, which can correspond to pretty much anything in the load-out, so that if you like, you're able to have 3 attachments for a gun at the expense of a few weapons. There are also Wildcard slots, which allow players to break certain rules - such as exceeding your limit of perks - though of course, there's a trade-off, in that they take up more slots. Simply, this gives players greater versatility to play online how they see fit, giving us the potential to make some zany combinations, such that again, one hopes Treyarch have bug-tested the Hell out of it, and also made sure things are adequately balanced to that end. Still, we have to say that having 6 perks sounds incredible; imagine the carnage you are going to be able to cause with that, stalking the map like a commando before, inevitably, someone mows you down with a miniature helicopter...
