To clarify, I am not saying that @ gametime 10min, there should be an option to remake.
I'm saying if the team with the leaver has the leaver disconnect, and survives (drag out the game) for 10 minutes (some arbitrary number) they have an option to remake. However, I know that remaking at that point is going to be a pain for the winning team, so they would be awarded LP compensation, the loosing team will get remake (or some soft LP deduction), and the main culprit would get the main brunt of the loss, since the afk was longer than 10 minutes. 10 minutes is a number that most people should be able to bounce back from if they accidentally DC due to glitches or something of the sort.
However it was brought to my attention that smurfs could possibly be abused in this fashion.
