This disconnect issue seems to happen mostly to Xbox players.
The crappy part is that when a guy in your team disconnects...then you have to play alone vs 2 players and its nearly impossible to win. But...after you lose that 1v2 game, you still lose your rank...and sometimes a lot of it(50%+).
I kind of agree with Xbox vs pc matches being unfair. I can't really imagine playing on Xbox using a controller.
Its "sad" whenever I see my teammate slowly "scroll/pan" from one side of the map to the other side, just to see where his units are and then pan the camera back to base to build some units/buildings, then scroll all the way across the map again, back to his units. Even funnier is when I ping a location and he tries to look what I'm showing...and scrolls over the ping location...then back again.
With a mouse, it takes less than a second to jump between locations on the minimap.
Also, i wonder if xbox even has control groups that are easy to use.
