Map was extremely hard to get even 5/5.. let alone 6/5
The balance was the issue that are most impossible to be solved. Also, by using naruto as the theme, it already lack of the originality.
Map isn't as easy as spells does where you just need to focus on scripting only.
It have more aspect than the current one you are listing at my vm.
I make a lot of map, I know how hard it was to perfect it. Map too compleks gameplay would probably make it difficult to earn DC, even too simple might not allowed it as well.
