I actually think it would make queue times better. You are in instances longer, plus not everyone would do the DF mashup. So you have the regular df and the df mashup. double the amount of queues. And to fight all bosses back to back for different bonuses/rewards/gear/etc. would be fun. Maybe even have something that rewards you for fastest completion, no deaths, random stuff like when dungeon queues, have an extra objective for the dungeon that nets extra exp/gil/better drop rates, etc. Like 3 back to back boss fights. First fight, satasha. Beat boss without hitting bubbles for extra tomes, then you go to Aurum Vale: Beat Boss with at least 2 stacks on every party member, etc. Add challenges to duties
