ARAM and AFK
I don't know what it is about ARAM, but 90% of the times I experience AFKs is on ARAM. People who sit in spawn with no items for the first 5-10 minutes of the game, people who rage quit out of the game half way through because they didn't carry, or people who are playing fine and then go and sit behind tower for 5 minutes not doing anything. It is meant to be a fun game mode, I get that, so I can see why people might not take it as seriously as normals or Ranked, but because it is a fun game how is it fair to anyone that 50% of the game have an AFK on one team or another. Even if the person who AFKs doesn't care, it ruins it for the other 4 people on the team who are almost guaranteed a loss now. Even if you ask them after what happened they just say that "it's ARAM no one cares, report away" and after experiencing this so much I have to agree. I have reported every AFK I have seen, on my team or the other, and not once have I received a response saying any of them got as punishment, but if we report someone for being toxic in chat in a normal, I'll get a punishment response in a few hours.
