More things they can do in the next new installment:
- More secret bosses like the boss in the mountains (won't spoil it).
- Bring back the whip (or add whip weapons) and hookshot as they'd fit in well in the new approach.
- Add cosmetic accessories that change things like Link's hair style like the male Gerudo outfit did.
- Some prior series items can be added mainly as sandbox options to play around with to add more options for situations for example the hawkeye could be introduced as an item which when equipped gives bows a boost in accuracy, range and damage while the bellow and beetle could also be added as utility items much like how the Korok leaf was.
