I could link games of Invasion Slayer where I've had 45+ kills and we lost. Likewise, I could link games where 4 or 5 people on my team dropped and I won 1v6 or 2v6.
It's pointless to show games like these and complain, because at some point every halfway decent player who plays alone has had a moment where they suddenly realize: I am the only one in this game who is doing anything. My team is profoundly and utterly worthless. We've all felt it, and there's nothing that can be done about it. Flaws in gameplay can be changed, flaws in the players cannot. You go in there alone, you deal with whatever happens, period. There is nothing to complain about.
