If youre a child that needs to go to school in the morning...
...don't load into a game just to quit it 5 minutes later because you have to leave for school--or anything in general that clearly does not allot you enough time to play. I mean if you know youve got to leave for something, be it for school, work, a sex change operation; if you know you cant stay for the whole game or even longer than 5 minutes, why load into a game? Why be trying to play at all? Is it really so bad to just go to a bot game, or load a custom game with bots?
"TRELOLOL UTZ N8T R4NKD HWQ C3RAS?!?!?" I certainly care because ranked or not i want to enjoy my time whatever mode it is. Sucks that you have school/work but don't ruin MY day off. It just makes you a complete dick going into a game when you KNOW you don't have enough time to play it. No one should do that for any reason. It's simply not fair to everyone else especially if they would be nice enough to do YOU that common courtesy. I'm not trying to mother my kid while i afk in your game; I play when i know i dont have to.
Edit: I understand some things spontaneously show up that need attention, and thats fine. What is not fine or justifiable is KNOWING you don't have any time to play, but youre trying to play anyway just to end up quitting the game shortly after it begins.
