Lol, okay. You must be one of THOSE people. The kind of person who can't play a game through because he gets too mad or starts losing and just up and quits. Okay, this makes a lot more sense now. Let me guess, you got banned in all the games that do punish people like you?
That is not enough, 2-3 minutes of uneven gameplay can end a game. Look at Dominion, heck a MINUTE of 5v6 can literally end the game. Games like CTF are the same, and even slayer to an extent.
You are the one without patience...
"Boo hoo hoo, I get banned because I leave all of the time because my mommy makes me do chores and then threatens to unplug my internet!"
^ what you sound like.
