The repetitive stuff is a great pick, the biggest problem of the game probably. Though I will say when I first played the game in 2013/14 I wasn't bothered by it lol It felt like a mystery that I was unraveling.
Man other than that it's tough. Bravely Second was a little snappier when going through the menus, that would be a minor thing to adjust in a rerelease. Same with being able to adjust the encounter rate without going to the menu. More asterisks are something they could never add enough of for me lol honestly it's hard to think of any major things I'd want them to change that you haven't mentioned.... Maybe additional outfits for the overworld that aren't tied to the asterisks? Could be fun
Now I wanna play BD again
