I think they should add in a deep dive fight. we have all seen the deep dive video. I think they should make the entire deep dive playable. as roxas you can take on all those neo shadows and once you have beat a certain amount of shadows, roxas will start to run up the tower and while running up the tower you can press triangle to slash the shadows that get in your way. once you get to a certain point Roxas will toss the keyblade to riku and together roxas and riku will finsh off the heartless. once the heartless are gone, you get a boss battle with riku. if you win, riku transforms into ansem. fight ansem in another boss battle like the one in kh when you fight leon, when it didnt matter if you won or lost, the story still continued. If you won you get alot of experience points and if you lost you go straight to a cutscence. im not sure if this has been thought up and posted yet but thats what i have been thinking.
