Doubt that’s entirely true. It might be that the game engine can’t do what is possible in other mmos. It would be hard to imagine a comparable system of unlocking flying in WoW. They’d have to give WoW players parachutes. But FFXIV’s unlocks don’t seem to affect their players’ opinion of FFXIV as much as the more cut-and-dry (emphasis on dry) pathfinder in WoW.
