After playing JP from release to Ep 4, and NA since May, and there are a few adjustments to the camera and visuals that I feel would be nice to have in game. A lot of these come from my experience with Ultimate Quests, but some additions would be nice regardless.
Increase the FoV of the camera or allow it to zoom out a few more steps than the current default. I find the current maximum zoomed out view to still be a bit too close to the character, and find myself getting smacked by a lot of things that are usually off screen/out of my FoV. Feels the worst if you're trying to focus on a boss (e.g. Anga, Drago Deadleon) that takes up your entire screen and there are those things that just come at you from off screen from the sides or behind your character (dog Anga tornadoes, anyone?). I get that a good chunk of this can be avoided if I 'git gud' with guarding and/or constantly moving...but that doesn't address the screen crunch issue I have.
Fix the camera tracking when a character moves vertically upward. Something minor, but sometimes when I use something like Gran Wave, Raging Waltz, or Symphonic Drive and my character moves upward, the camera doesn't follow and my character moves off screen.
