I haven't had too many bad bugs show up for me. I have been kicked out of the server a few times, but that's to be expected with EA servers. I also had a few problems with weapon attachments not unlocking.
I don't think the graphics are too bad. They're not the greatest looking ever, but I don't think they're awful. The gun camos could use some work though.
Props to Rajeanero for the avatar and Gackt for the sig.
