this is why we always played invasion! all those small maps suck!

I have this question. If we have a player who has ran the map 100s of times , has a zen (no recoil) and slides mom a 20 to put on her card is now got the tools to be ungodly in cod. Now the kid whom goes to school everyday to listen to 30 plus kills at the lunch table get shit on. U can buy cod. Play the game for five minutes youll get sniped once or twice outta no where or from a sniper across the map. Then one or two shots kill you like you dont see them until replay. Why is it latency of the server? My wifi is fast im a stock broker i have to have speed. Im just wondering if theres gonna be a match i can jump in that i know the other players are on my level but thats a perfect world. I just have lost interest in trying to keep up its impossible unless you dedicate your life to the game.?.?.?
