I've noticed this happening a few times too, which is amazingly annoying as well.
It seems that people, in an attempt to stop letting the loyalists win all the time, have gone to the polar opposite.
I thought about giving a long winded reason, but realized most people wouldn't read it, due to the fact of it's unnecessary length.
So, basically. Yeah.
As stated above, BF3 kinda was better, just as it looks more polished IMO.
That said, I enjoy jumping on the 360 from time to time, and waving around my Captain America emblem into people's faces when they get killed.
That's always fun.
