I think you guys bring up a good point here, I definitely feel that the current dungeons are way too easy. They are more or less all speed runs.
But then again, lets just say SE develops this dungeons which are longer (making it feel more crunchy/raidy/engaging) with "harder" bosses.
What would the incentive be?
As in, what would be the reward for players to want to this longer, harder dungeons, rather than the boring, but short dungeons?
Dont say minions, or mounts, because those only work for a short while until everyone has the rewards and the dungeon just dies.
Also keep in mind that this probably wont be included in DF because of its length/difficulty
