All of the snipers from mw2 who hated black ops will be on mw3. All of them. They all use quickdraw and it's super effective on the sniper. I snipe from time to time myself and I understand why they made quickscoping so strong in this game. If it was like blops sniping, then the weapon would be really weak because of how small the maps are. It needs to match the pace of the other guns, since everything else kills in about 3 bullets. Understandably, some people will not like mw3 because of the sniping.
I suggest the type 95 as a counter to the quickscopers. It's a very accurate 1 burst kill weapon that makes snipers rage. Also, be sure to use the ballistic vest kill streak to piss them off even more! The good news is, if they're using quickdraw it means they're not using assassin, so feel free to spam the hell out of those UAVs using the support package. I want GAF to dominate these guys. Everyone please use the GAF gamertag as often as possible so that we party up, party on, and eradicate this plague that will be upon us tomorrow.
This time is the best time of year for COD because it's fresh and new. I'll probably grind through the ranks for the first month or so. By February, the game will be filled with heartbeat sensors, assassins and quickscopers, so have fun now while you can dudes!
