Ranked LP Loss

Just a quick concept. The game automatically announces when a player has been unmoving for a period of time. How come Riot has not implemented a system to where when that happens that you cannot lose LP if you surrender or something close. The game knows when you have to deal with an AFK member (more than just someone dodging for a period of time) it should give you the option right after that announcement to remake or quit once a timer has been reached. I know people will take advantage but it is MUCH better than to deal with people inting or quitting and losing games from something you cannot control.
