Big and open, multiple different paths spread about with coffers full of dyeable gear or a minion to give a good reason to explore, plenty of enemies too if someone’s looking for extra XP, but I would definitely have a way to get to the end quickly, you’re not always gonna be in a exploring mood.

Theme of the dungeon is a little trickier, if we’re staying in the realm of 14 then I’d maybe go with a Garlean theme, Iike a better, smaller Castrum with more freedom, some verticality too. If this was just a dungeon in any MMO or RPG then it’s hard to say, but I’d definitely want something with either lots of colour, or a cold, frigid dungeon.
