Player is using some kind of aimbot, one of our members (he is a competitive infantry player) was going against him and he was looking at the wall then he flicked and headshotted him (i was spectating this). His stats seem low, he is doing a good job at keeping them low, however, a lot of players have been complaining about him aimbotting for the past three rounds, and he has run some pretty high killing strikes for somebody his level. I do not believe he is legit. Also, this is from BF4stats:
