Consodering there are people that runs alts with the purpose of letting eventual rivals for first place lose a lot of time i am indeed on your side in that sense, but more than reducing the time i would just grant more points if your fight is long. An 8 minutes fight won, imho, should deliver 8k points to the winner and 8stacks of rage with 0 moral points lost to the loser since is actually a draw more than a win.
