My personal disappointment is that the current level 50 dungeons aren't giving EXP, unless they're run in Roulette. Which, I mean, sure, I'll happily do Roulette for EXP, and I know it helps out new players who haven't cleared those dungeons yet! Which is fantastic. But, it's going to sting when I party up for friends to help them clear those dungeons, or even for those doing those dungeons for the first time.
There are legit tanks who swap on Dexterity accessories because it supposedly helps them Parry.
I think you can sort of understand where this is going. It's just very awkward.
The airship crafting system brings back Materia in the example screenshot. And while FC crafting is a thing that is, ultimately, FC-based... there's supposed to be personal airships in the future.
