The only time I drop party, is if there is like 5 minutes left and weve wiped repeatedly on the same boss, say five or more times. I do however think there should be a longer dbuff time for those people, like the above person, who enter the dungeon, see its a full run and drop out. That leaves the other members waiting twice the amount of time to get a new tank or healer. I think, if the tank or healer drops out in, say, the first 15 minutes of the dungeon, then their debuff should be maybe 24 hours. That would solve that problem. If you are too lazy to spend the 20-30 minutes it takes to run the dungeon, then just uninstall now. Noone is going to want that lazy attitude in their group or FC.
