Is it the time to make something other than lower queue?

When I play a rank game last night, the enemy's team had 2 AFK player. Then their mid player Zed said that "riot need to do something with afk other than lower queue." That is the question what I am also thinking about in these few weeks. Because of these two afk players they lost and my team won this game in a very boring way and zed was angry because he lost LP in this stupid way. The point I want to say that is Setting the lower queue is useless. The AFK player do not care those 10 minutes or 20 minutes, because they can watch some video when they are waiting the game or do some other thing. So I think that the player will lose 1.5 times or twice times LP if they AFK without any reason might be a better way to punished those AFK player. Moreover, another players who finish the game just lose half or 75% LP might be fair to these loyalty players. LP is the only thing we can gain or lose in the rank game, so I prefer reducing more LP rather than making the lower queue. Playing in a better game environment is our wish. So it is time to make some change to punished AFK player in a more stringent way.

Thank You
