The wraps change to twf die boost is only natural and should have come that way to start honestly. Really, it never should have made it off lama, it was obvious to everyone.
The henshin mp reduction is only natural and should have come that way to start honestly. I'm not saying staff is too strong, but this much melee power this easy is too much. They need to buff staves in another way, such as giving the weapon line damage boosts closer to kensei levels, giving boosts to the clickies, etc.
I think you could have left the heshin 18 core and capstone at 10/25, it's the dipping that's the major issue after all. Is there going to be a corresponding reduction in the shintao 18 core and capstone? or just don't change the henshin 18/cap.
