I know what you mean. The only problem as of late for me is that the only game type I like (Wingman) is impossible to find a game of most times. It is the only game type for me that does not start lagging like a B. Wingman is the only game-type that functions properly on Gears 2. But I haven't played for a while, so when I get back on, I hope I will be able to find games for WM.
