Stop Complaining About AFKs In Matches (short rant)
Yes, having AFK players sucks. No, there is nothing Riot can do about it.
The only 2 things Riot could do is either : Give every player perfect internet providers and amazing computers. Or If they somehow magically force every AFK player to play their matches.
I don't see either one happening, especially the 2nd one, so grow up and stop blaming Riot for this happening and telling them to fix it or give you your LP back. Do you think LoL is the only game with this problem? It's a PvP video game, this kind of problem will exist in 90+% of PvP video games.
Go play matches instead of wasting time whining on the boards about how it's unfair and only happens to you.
Rant Over.
