1st) Remove the bot catchers at Encounter with the Buddha and Subway: Line 1 where the Wraiths are. Why? Because both places are good for training.
2nd) Add more boss maps like Samurai Knight, Anego, Dodo, Lillinof, Raika and maybe the ones at Neo Tokyo like Vergamot.
3rd) Add an etc call Lady Boss's Comb to the item seller at Free Market. Why? To summon Big Boss at the NightMarish Last Days of course! Whats the use of adding this boss map but not getting to kill the boss. By the way, Anego does not drop anything
