TBH, I love how HoN did it. And it's not abused there when it comes to rating.
Once you DC a timer starts ticking. After 5 min your champ is removed and the items are dropped on the ground for your team to sell/use and the gold is split.
After 2 people leave and it's a 3v5 the game goes BLAH BLAH U CAN NOW LEAVE IF U WANT WITHOUT PENALTY FOR LEAVING. <- No more stats recorded after this point.
But you don't have to. You can keep playing and make the other team rage as they can't leave until the game is over (usually quickly as your team leaves asap) but you can hang around doing 1v5 just to piss them off. Its hilarious.
