Well it's your fault really. Why don't you just let the man quit if they are getting spanked? Unless you are hunting for favor points, there is no point in insisting that the other team stays in the game after defeat is certain.
What Izzo said.
Quoted for truth. If the outcome is certain, why should you care if they stay in the game. You still get your reward.
Theres a big difference between ragequitting early in the game, and conceding when defeat is certain, and for some reason a lot of the people on these forums cant seem to tell the difference.
At least we will get the concede button in a patch or two, and hopefully then people wont expect their opponents to stand there and get beaten to a pulp for 20 mins.
