Rage Quitters

So I was in my Gold 4 Promos on my last game of the series, and we had a significant problem that lost us the game. Our Top laner Irelia after 2 deaths top straight up flamed us and then quit at about 5 minutes in. She never came back. So from the 5 minute mark, it was a 4v5 with a fed Mundo on the other team. I'm still baffled at this persons reaction to dying twice. As much as our team tried to stay in the game, as much as I tried my butt off to win, it was to no avail. We had a significant disadvantage from the get go. I lost my series, and my LP over a rage quitter. I think I've mentioned this before, but the remake system still doesn't cover things like this even though its still a death sentence when it happens. There should be a system in place that allows a remake after an extended period of time that someone is DC'd. We have the "remake if someone hasn't connected after 3 minutes, but we should have a "remake if a player hasn't come back after several minutes" option. I've been screwed over so many times since the Inception of Remake because of people quitting after 3 minutes and not coming back. Chances are, if a player is still Dc'd after 7 minutes, they aren't coming back, which hinders the team it happens to greatly. As grateful for the Remake feature as I am, it can do to be expanded upon.
