I feel your pain. I am always the one with the most kills, most headshots, most revives and least downs. From experience i have found that 2 people who share the same console tend to be the worst as player 2 almost always is terrible. Just keep backing out of the lobbies until you find a decently ranked bunch.
Lol. Ok so when I don't have one of my 4 or so friends on who are nearly as good as me, I will poll and invite until I I have a lobby of all skull-ranked players with mics. I did this for the umpteenth time just now on farm. I had as many kills as all 3 of them combined, with 33 revives using nothing but the mp5 and galvaknuckles. They cried about not having the right weapons... They always do... I hadn't hit the box yet.
Seriously, I'm very modest ingame, the only reason the topic is named as it is is because I'm really trying to attract the attention of some above average players. This is the only game I've been playing lately so I'm on a lot.
