For me and what I hear it seems to have gone from barely working to kind of working.  I had almost zero luck even joining servers before and while I can join now, it freezes and crashes often.  I also don't see ping for any servers in the browser.

Good day gentlemen!  I step into your humble abode.  I am a seeker of BF2 that actually works as the new "patches" are absolutely deplorable!  I hope to find good MP here forthwith!  Cheers!
