In a few games, I have gotten players who wont communicate at all let alone concede. 

Now I wont concede as soon as ive determined we cant win, but usually a few min later just to be sure.  In the above case, my team doesnt talk at all, or work together, let alone agree to concede.

I will then tell the other team gg, my team wont talk, and wont concede. This is not a rage, I just wanted to say gg before I leave to get onto my next game, as the current one is over (even though it could go on for a while longer, still resulting im my loss). 

I have been flamed bad for doing this by the other team.  All I can figure is that they want a to stomp and not have a fight.  I mean when you are 4 lvl warscore, and 10 kills behind what the point.  especially if the other team is coordinated and yours wont even chat at all.

So am I just stupid noob kid that deserves to be flamed for saying gg, and that im out so I can get into a new game, or not?
