Which is why I suggest a 'Mistral Ballad' version of the dungeons. Difficulty will recommend players to be around i105 and the rewards will be treated similarly to Walk of Echoes in FFXI. Every boss you beat, four chests will drop, one for each player. In the chests will be a dyeable dungeon equip (say you do Lost City. The gear that is not Darklight can be dyed), an untradeable dye, a Poetic crafting mat, ten Ventures and a 30-50% chance of i115 equipment dropping. For the final boss, exact same thing, but this time the fifth chest will either have a 30-50% chance at dropping i115 gear, or a 5-10% chance at dropping i125 gear. For giggles, there can be a 1% chance of a fifth chest appearing that will drop a i130 weapon.
