Should you be penalized for AFK'S in your ranked games?

League of Legends is an online MOBA game for everyone to login to and enjoy playing. However, this fun runs out when one person doesn't connect to your game or leaves in the middle of it. While there are connection issues that many players have with bad internet/routers/older hardware, there are many that just leave because they have to something. I have heard many really bad excuses, including these excuses that have appeared in my games:

• "brb, I have to go shovel something"
• "im really sorry, but drunky make me come, i eat rice real quicky"

By this point, the game isn't fun any more. To make matters worse, this all occurs in my ranked games! Should you be penalized for someone AFK'ing in your ranked match? I honestly hate the fact that you lose 20 LP just because someone decides to deliberately disconnect from the game.

My standing is why can't those players affected from AFK's get Loss Prevented? I don't know how many games that I have lost that come from this despite the fact that all lanes win lane except for the lane that had the AFK. While I do realize that there are measures in place to ensure that a team isn't "completely taken out of the game," but all the enemy has to do is group at all! And you know that it's a problem when you ask for a report on the AFK player, one enemy asks why, and another one said "The AFK, duh. Why do you think the game was so ez."

This is a really annoying issue and I would like to hopefully reach a compromise with the makers of Riot Games. I do not feel that it is fair that all players who play the game should be penalized for AFK's of a certain time limit. You do have those players that disconnect for 5-10 minutes with internet/hardware related issues, but once it reaches a certain amount of time, it becomes quite clear that the AFK player is not coming back and you are just stuck with an unwinnable 4v5.

Below is a link to one of the matches I am referring to: a Lulu that AFK'd at level 4. While it is understandable that such a system may be difficult to work out, I feel that it would benefit the overall security of all players in a game. Please post your comments/remarks of anything that you think could be helpful and help get the attention of Riot. http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1886957706/205975797
