After level 20 things go smoother, if you prestige, the fun starts all over.
Don't play TDM, it's where the horror is at, if you don't like camping, don't play the game.
Camping isn't weak or noob, you can counter it ( campers stay at/near one spot, use stun nades & semtex/frag/crossbow/grenade launcher and campers die miraculously ).
Don't hate the player, hate the game instead, it's a design flaw that such a thing is possible and the lack of outside the box thinking by you 'haters'.
I've prestiged in no-time, found a smooth way to play (S&D is my main game. It provides fast leveling/codpoints, if you die you can learn from others and it's always different).
Try out different guns, perks and whatever, this ain't MW2 or BF:BC2, this is black ops, each and every thing is different, yet improved in a lot of aspects.
Oh and AK74U might be slightly overpowered, but I use it and rape people with it non-stop, so I don't care.
