The current battle system mainly calculate everything from Your Rank vs Mob Rank

But its not a combat system... It's a stat system. Two different things.

I'm not sure what your point here is.
My point was that the new combat system will very likely use the same stats in a different way, so any work analyzing the current state of the game would not be useful in the long run ( as interesting as it might be to some ).

The application of stats in calculating damage is part of the combat system.
