I think if someone dcs you should be allowed to afk without fear of punishment
When playing league you hit the queue up button which says you are signing up to play a 5v5 game. IN no way am i agreeing to play a 4v5 and or put in any effort. SImply because a botlane thinks he can carry doesnt mean i should be forced to play a game i didnt sign up for. And punishing those who are victims of trolls/afks/dcs just puts the blame on those who in no way agreed to that.
