Your net issues plus Kawusa being a top FPS player is the problem.
Let's be honest for a mo, most OcUK guys are half decent and know how to play the game in public. Kawusa has around 3 years of top tier competitive BF experience on top of being naturally good at all FPS games. He is not a "casual scrub" he is one of the best players in BF. It is hardly surprising that you think he is a hacker, however his stats and streams have shown he isn't.
Kawusa has a wealth of knowledge and is a nice guy that is willing to share tips. He should be learnt from not derided.
Edit..yeah 2 posts FTW
OMG... Common sense. Please don't post this, it hurts my eyes!
Kawusa is a confirmed hacker. The other day I was behind him as he was prone. I shot him in the head 680 times (I know this because I counted each shot as I've played FPS since CoD 1) he ate every shot, turned around, and one shotted me with a flare. I reported him after I went 10-17.
Many lollies.
