In 100% of my matches last night, the hosting team won, and the actual host finished in 1st place. It's like one team has God mode enabled basically. You can put a hundred rounds into somebody and they will just turn and kill you in the blink of an eye. It's so frustrating!
It also svcks all the fun out of the game knowing who's going to win before it even starts. And for the record, it's not being owned a I have a problem with. I think it's lame when we get the advantage as well. Heck I was host several times and while I did feel like a beast, it was just completely unfair. I like skill to be the determining factor when I play online. That's one reason I sold Black Ops a few months ago.
I absolutely love every other thing about the game. If thie one issue could be resolved I will be playing for a logn time. If not, it's going back pronto.
Edit: I'm playing on the PS3 so I don't know if it's the same for the other platforms.
