Ok, just to get a clear answer regarding initiative - does it matter at all?

For example, one of my ninjas has more initiative than said opposing ninja, but he goes first anyways.

WTF?

Other than the refined stats, are there hidden stats that we don't know about?

If what you say is true, I'm guessing every ninja has a hidden initiative stat along with everything else? The real question is, how do we find out?

RNGesus ftw. :(
