If you have someone DC in game you should get loss prevented.

Why is it that when you lose because its 4vs5 you still lose LP? Yeah there is a chance you might come back but that's almost never the case. Yes you can report them afterwards and they get leave busted but what does that do for the 4 people that tried their best but still lose after 30-45 min because this guy has internet issues? I understand that it may not be this guys fault that he DC but the 4 other people left in the game has no choice but to play it out and try to win but the end result is that they are going to waste 30-45 min of their lives for nothing. AT LEAST riot dont make them lose LP.
