Its too hard to find a game online at the hours I play. Since you can't join in session, and hardly any are playing anyway, it can be 10 minutes between rounds sometimes, and I get so little time to play anyway I don't want to spend half of it sitting in a lobby waiting
The patch will help for sure, as those who truly care about the kill count have been frustrated (I see why though I just play to play). The cost of the DLC I have to say is nuts now. 400 was debateable, but 800 isn't going to happen. That I imagine will turn people off to it even quicker.
I'm still lurking, waiting for word of a patch, then I'll give it another go (need that low res / hi res model fix so I can see the enemy!).
