I'm in low-priority queue because I decided to move in with my Grandmother and take care of her.
That's about it. If she randomly decides to call me while I'm in the middle of a game, I have to drop the game and go help her. It's not something I can prepare for, hence the random. Which means out of 20 games I'll have to AFK in maybe 2 of them. Shit outta luck because the system doesn't give a damn. [sg-miss-fortune] It sucks, but that's life.
Edito: A thought came to mind. Why does Leaver Buster exist when you can report someone for AFK?
