Like to see Job Dungeons appear that require say 8 White Mages or 8 Dragoons or Warriors. Each Dungeon has its own boss and reward the job your using it for.
It can be the same dungeon but enemy layout/boss weaknesses/rewards/pathways can change. Its since to see many people take different roles while on the same job, Such as White Mage Melee,Cure,Magic Nuking etc.

Can also be creative like a Melee only chamber & a magic only chamber.
Would also like to see some Job locks while inside the dungeons.
