Just lost a Beastmoon match because one of our players suddenly-without any explanation or warning-went AFK. Now, I understand that things come up, and if you need to AFK, and you let your team know, fine. Come back ASAP. But to just start spinning under a bridge without telling anyone is absolutely not okay. It's also really rude.
I rarely if ever report players. But I feel that going AFK without explanation-and never returning to the match-should be a reportable offense.
