I wouldn't afk often, it happens once in a blue moon but there is a point where you are in solo que and there is nothing you can do and the enemy team wont finish on purpose. It's a waste of time, a lot of time, I'm talking about the 60 min 80 min games that go on cuz the enemy team has to get every objective 400 times and your team is legit griefing. Maybe setting a maximum time for games could help like maybe 1 hour and then the # of people required to surrender would diminish? Something like that could help with a lot of the grief in these scenarios. If you can't win in a game in an hour and the enemy has ALL their towers up.
Anyway I just wanted this to be a serious discussion but everyone in here is derailing me telling me "there is never an excuse to afk" well then this community is just a bunch of griefers then. Never ff is toxic.
Also i have never afk'ed ever.
