Okay, jokes aside, I've just been getting back into this game, even though I don't play it on 360, classes are classes.
Ksg - long barrel M1216 - long barrel Lightweight Toughness, scavenger Dexterity Overkill Perk 2 greed
It takes a bit of getting used to, but if u are good with the ksg no probs. Honestly scav + perk greed can be switched out for anything, I just like knowing the m1216 will stay full. Ksg for mid to long range if you can manage it, m12 for cqc. This class and nuke town or any of the smaller maps is just plain fun.
