BF4 shitty Netcode or what?

Playing a bit today, I noticed that the specific enemy player was killing me way too fast... Thus I started recording the game. See for yourselves how it feels playing against him! He has 100% accuracy, even if not knowing my position, even if he is suppressed, even if he is getting hits... And by looking at his profile, with ACE 23 he has just 13.15% accuracy, while me with M16A4 I have 17.77% accuracy (way better!). It's like BF4 NETCODE is messed up!.. And this makes the game really unbalance. Specially when this scenario happens too often for me!
