1. Inventory issue
2. Better endgame gear designs
3. More casual raids like Crystal Tower. Enough with the Void Ark style raid that wasn't inspired by older FFs.
4. More revealing gears for healer. No more nun robes.
5. No more tightboots or high legboots or whatever you call it in English.
6. More skirts, less trousers.
7. No more clothes with clipping issue. Some of 3.2 gears have my hand(s) clipped in the cloth just by standing. It's terrible. Clipping while running or fighting is one thing but clipping while standing is terrible.
8. Make crafters/crafting less important. At least take them far away from raiders.
9. Class Zero uniform.
10. Serah Farron's hair and outfit.
