Attack, defense, and recovery formulas

In many cases, the calculation formula due to the change of the item is unsatisfactory for some reason. I want you to change the calculation formula to be displayed in the menu of Diablo3.

There are examples of builds on various sites, and even if I change items based on them, it does not become the reference example.
It seems there is something wrong with it.
The video of GR on Youtube is also very unpleasant because the defense and attack power have changed too much.
Too funny!
