Sorry, i probably should have clarified. xD I actually disagree with OP about changing the KO rule. I think that's awesome ... although i agree that the problem of getting a KO count on disconnect is an issue to be looked at.
My problem is the forced fixed party system. Even FFXI wasn't that stupid most of the time. There's a difference between 'challenge' and 'stupid'. If SE is determined to have this operate without Duty Finder, fine, but let us change members freely every 10 floors. People pop in the purgatory room anyway, and the pool of people to go on with or invite will be drawn from those who still have a 0 count. Simple. Done. Like if you were fighting Kirin in Sky and someone bails, you can still go shout for a replacement. It doesn't change the fact you were gunna be up there all night for the fight...
