Why can't Dungeons be longer/harder, but more... piecework?

[Floortank]

You can't invent new dungeon systems if you don't understand why the current dungeons are the way they are. And I know you don't understand that, because your replacement causes a lot of problems that the current design addresses.

You may not like the "fast food" approach to dungeons in XIV, but they are built for efficiency on the service end--to get as many players participating in and completing content as possible. To do this, they're relatively short and relatively similar to one another, with a few exciting but simple variations, so that by learning one, you have a good idea of how to do the next, even if you've never done it.

Edit: I'd go for a big crazy dungeon you can do all at once, or in shorter segments, saving your progress like Palace of the Dead, 1000%, but I wouldn't want that to replace the regular dungeon grind or tomestone farming method. Supplement it? Sure.
