- Expand item shortcut slots.
Good. That was on many people's wishlist, it seems.

- Adjust the drop rate for equipment.
I hope that means less drops, but higher quality.

- Change the conditions under which the player character becomes unresponsive when the Ki Gauge is empty.
Hmmm.

Implement a flow to allow players to exit a mission.
Yes, please. I was surprised that I couldn't exit back to the world map again after revisiting the first area upon completing it.

Reading those comments at gematsu, it seems a lot are more concerned of the changes than happy about them, and asians seems to be the most that's having a hard time with the game lol.
