The thing is, even though the story wasn't left out, the character development was. Even though the story mode sometimes has some really good moments (Labrys and Elizabeth are good examples) but other than that i felt pretty indifferent for the other characters story mode, it's like they didn't really get more close after persona's 4 story, and a few times the story mode is just an excuse for the fighting between characters.
Long story short :
This is just my opinion though, but i am really disappointed because i truly love persona 4 (both the game and the anime, they are both amazing) but this game doesn't has what makes persona great.
