It seems like they've done something horrible with the netcode in the .18 hotfix I'd seen reports of it being unplayable. The previous night was half and half, but totally described how it was for me last night.
I had a few games yesterday, was having lots of trouble getting into games, kept telling me the MW3 servers were too busy, and the leaderboards were mucked up to hell!

I think many people are starting to feel that the game is stale, boring and full of utter crap. I mean it's been out 2 months and the game is still full of issues and as they fix older problems new ones just pop up over night and some will never be fixed at all.
