Do something about the AFK'S!!
The amount of AFK's I have been getting has made League of Legends unenjoyable. I dread playing because I have this dark feeling in my gut that one of my teammates is going to leave. The reason is not the issue at the moment - it is the fact that people leave so much that League is basically no longer fun. Most of my games are lost from the very beginning because someone left or never showed up. Riot needs to figure something out.
We always talk about punishment. That still needs to happen - BUT, just punishing the wrong-doers isn't helping those of us who get fucked.
One person suggested something about gold distribution - I suppose DOTA does this? I wouldn't know. So, basically, the person who is gone, their gold would distribute to their teammates or something along those lines.
I'm sure the community can think up better ideas.... Something has to change.
