FATES is the new way to exp. exp is your reward. Bonus that you get items here and there, seals/gil too.

Of course it's going to get boring if you are using FATES as your sole means of leveling up. Anything you do will feel the same, what's good is that there is some variation in which way people can choose to level.

Hoping EXP parties make a return soon, not had a single invite in 3 days of putting my flag up for it. Maybe i just need to stop being lazy and make one myself
