I was playing this week and got called a hacker a number of times, I didn't notice anyone else did during those games. A few were pretty excited about what I was doing, but I wasn't aware using a starting level LMG and mowing down idiots who bottle neck was considered a hack..... I routinley have a top 3 score in BF3 and I am very low level. I think most people don' tunderstand these games and generally don't really know how to play. I constantly drop packs for teammates in fire fights and my score looks like the national debt clock. I also lay down a lot of fire to let my team move up and will ambush the enemy at cap points.
I dunno. The game is pretty simple, not sure why so many people suck at it. I didn't see any scores or KD that indicated cheaters - but there are 2 million more players now than last month, so them being new is probably helping my score. hahahhaha
