I swear, if I had a penny for every time all 3 other members of my team left the match cause they thought they we're losing... And the funny thing is that leaving actually has a penalty for the players but they still do it! I don't understand. Is it like fans can't deal with loss, or are they impatient and want immediate results? Are they worried about their win/loss stats? Their KD ratio?
I'd rather play up against 4 other people all by myself and try my best, than to quit and leave my teammates alone. It's part of the play, you get some losses and some wins in the process. Sometimes you get newbie teammates who just started playing the game while the enemy team is very well-coordinated, you can't control those situations (that is, if you don't have a group of professional friends to play with).
So instead of just running away, even if you're not doing well in a match, at least try to help your team get score and finish the game that way. You might even get a comeback, who knows?
Sometimes, the game crashes and turns the xbox off. I know its a bug that relates to the weapon and vehicle skins, but man it drives me insane! I know that it affects pretty much everyone and can happen at random. I assume that’s why sometimes you end up with a 3v4 team. As for other people, I guess they just get frustrated or don’t like the game type/ map
