URF observations and comments on a leaver kick system.

Please make URF a permanent game mode!

An observation: Out of at least 25 games of URF, I didn't experience a single failure to connect/AFK/leaver on either my team or the enemy team. In normals and ARAM I'd say I see these in about 1/3 or 1/4 of games. Coincidence? Possibly, but I don't think so. People love URF. But also.. RIOT needs to implement an afk/leaver kick system. Games are more often than not RUINED by the absence of one player.. and the other 4 teammates are left with a lot of wasted time. WoW implemented a leaver kick system years ago and it worked great. I understand that League doesn't operate as WoW BGs do, but for League the new player could be placed into the game with an average of their teammates' levels and gold to make it fair. I feel this would be a great addition to this game that we all love.
