=Survival Mode!!!=
The history of video games is full of "hopeless causes"
Space invaders
pacman
Asteroids

Many x - box games have a "survival mode" where the point is to hold out as long as you can, knowing that you are going to eventually be overrun. Why not here?
The servers dish up uneven games all the time. Even a balanced game can turn lopsided any moment. Why complain or quit? Some of my favorite games have been while heavily outnumbered. It gets my adrenaline flowing and amazing things can happen!
Give it a try. There is no shame in losing. Why do games have to go on as a protracted stalemate to be a "good one"? I don't know how many times I've seen people switch sides just to see things go lopsided the other way. I don't hold anything against the other team for the luck of the draw.
If you want to switch to make a more balanced game feel free but don't do it for my sake. Don't get me wrong, I like the help I just don't have a problem with letting a game end.
