I agree about the pacing of the game. Some of these maps I can run around for almost two minutes without seeing anyone, then I get shot in the back. I know the spawns and put up decent games regularly, but the pace some of these games can get a bit frustrating.
Knowing spawns and using turtle beaches can only help so much. When people are using more of a camper play style, knowing spawns doesn't help much, because they don't die. Headsets don't help much with people who are not moving.
