It's really easy to use.

use the google translate
but still, I would love to see they update our simulator since china ver have many differents skill th*
admin pls

It is something that should be updated more as we go but I do agree Akasha. It isn't that tough to use unless you're trying to implement ninja that aren't in our version, which is * and a waste of time. Then again I never found the use in the combo builder, it's pretty easy to just pick the ninja you want in your team and visualize the best combo/positions.

the problem im having is that google translate is preventing the list of ninjas from working correctly for me. when i translate the site the list is always blank. even when i try and select a specific ninja group or attribute.
