Riot needs to address dc'ing in games

So I was in an ARAM game, and disconnected in the pre-game lobby. I try and exit out of the game to dodge, and the game closes. I think I've successfully dodged. After a little while I try and log back in, only to find that the match I dodged was still going on. How hard is it to have a game cancel if someone isn't connected in the pre-game lobby? Thankfully this was just an ARAM game and not a ranked match. This kind of thing should really be fixed. It isn't a complex idea. If someone isn't connected in the pre-game, don't have the game start at all. I'm sure everyone in the match would rather go back in queue than have a game with a dc.
