Well if by the time Im done with all the games I've already pre-ordered and the game is overwhelmed with quickscopers then I just won't buy it. Im content with Blops as my CoD of choice for the time being.
QSrs never bother me. Mostly easy kills. My son has played tons of hours in private lobbies QSing, so bring it back for him, I could care less. There were way more other problems in MW2 besides QSing............../facepalm.
