Haven't watched him but I'm running into these exact issues, I'll win 2-3 in a row without any quitters, the next game we'll just be up by like 20 kills and the other team all quits and boom rank goes down after one loss. Then it takes another 2-3 wins to get it back up and you have to be like slow down guys we don't want to beat them by to much. Such a ridiculous game, you'd think they'd fix these rank issues since ranks=halo.
I feel like I can't win here. If you quit out of games you rank down, if the other team members all quit out and you go into a black screen momentarily while it ends the game you still rank down! What gives? Now when I'm doing really well I just sit there and hope the other team doesn't quit, what a messed up and frustrating system.You watch TomComingAtcha on YouTube? He and his friends are having the exact same problem. Tom alone is only about a 20 when he should be a 40.
I know it sucks, but the only way to prevent the quitters from leaving is to give in to them and make them think they're going to win. Then, when the score is, say, 40-30, wipe them out.
