And add more OF them.

Why not have MULTIPLE Duel Lv 10s? You'd have one each against the following ships:

Yamato

Iowa

Nelson

Vanguard

Bismark*

( * = these two were hidden in the game's data, and I managed to hack them in once, but it seems Phyzios didn't like that and so left the placeholders, but deleted the data needed to make the ships, and that's why we can't have nice things)
