No idea about your buddies host, but lag comp is no different in this game than it is in any online game ever made. It is in no way the cause of the issues people complain about, even though to laymans logic it is, and I'll admit I can understand how people come to that conclusion; the 'lag comp problems' people have are actually caused by bad ping lobbies. Simple as that. And theres not much you can do to improve what you find, other than find what time period offers up the best lobbies for you. For me things get quite ropey roundabout 1am. If I have a bad lobby I let the match play out, back out after and find a new one.
