this is going in the 2.1 patch
AFK Lobby Hosts
It’s no fun being stuck waiting on lobby hosts who have seemingly abandoned their duty to get the game started. We understand that this can be a frustrating experience, which is why we've implemented a process to boot inactive players from public Arcade and Custom Game lobbies, whether or not they're the host.
Players in public game lobbies will now be prompted to respond after a short period of inactivity and will be kicked from the lobby if they remain unresponsive. If the booted player was the lobby host, a new host will be selected from the remaining players so that you can get back to the action as soon as possible.
i am hoping to see a lot less afkers in game (except me when im jester or neutral who doesnt give a fuck XD)
