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

And my point was that you cant assume that they're changing everything in one fell swoop. They could bandaid a new combat system and leave stats intact and let it work itself out.

And that invalidates my point how? "My point was that the new combat system will very likely use the same stats in a different way" - almost the exact same thing you just said.

I simply don't wish to start experimenting to reverse engineer the equations until we have a finalized system in place. And the words "very likely" were there to indicate that I was speculating to some degree.
