Dungeons and Kill Exp: Generally undertuned, and exclusive with forming a party or even using your chocobo in combat. When dungeons give poor exp for the time investment, why would someone do them over forming a party for much faster FATEs? If open world and dungeon queues gave better exp, people would consider it an option. I want to get my Chocobo's Rank up but I constantly have to fight with the fact that I cannot queue for an instance while doing so, and I often have to compete with grouped players for my fair share of FATE exp.

Players don't FATE grind because they WANT to, they FATE grind because they're FORCED to.
