I'm a bit mixed about BO2 as well, haven't really experienced the sniping like you but I agree completely with the single player. I haven't got a clue what's going on at all, it reminds me of Sniper:Ghost Warrior's campaign, that was a bit clueless except with this it's switching between eras with no real structure so it's very confusing. It seems that they expect you to memorise everything from the previous Black Ops in order to understand what's going on here, I feel sorry for those who haven't played it as it must be a lot worse for them.
