IF and WHEN I can now find a "stable" ranked US server, I can only play a few rounds (or less) before being kicked.  When I try to go back into the server, it says I'm banned.  Sometimes it will take a few rounds, and sometimes, like I just now experienced, I was kicked right after got in and killed 1 player.  Also, my ping has always been under 70 in these servers.  It especially svcks if I'd had a great few rounds and unlocked some stuff and gained a level, only to have it taken away once I'm kicked.
Now, I'd understand if I was going 20-0 on every match and people thought I was hacking, but I can barely maintain a 1:1 K/D ratio.  Is this just part of the general broken MP problems, or is this a new grief trend with server admins?  It seems to have only started in the past few days.
Crytek, please...we've been waiting to have the "full" Crysis 2 Experience since launch.  I'm getting to the point where I'd just like my $64.19 returned to me and check back when you have it sorted.
