And that is precisely what is wrong with ideas.
How you would replicate all that martial arts attacks in mmo game without ruining internet for everybody else?
Look at Tera, it probably has closest (in mmos) combat mechanics to what you want achieve, yet its very far from it, and on release it was pushing what is possible for mmo.
It is not about what you do with numbers, it is about how you replicate (send to everybody who needs) them fast for sometimes hundreds of clients.
Very often great ideas just cannot be implemented. For eg. “Stable mmo economy” is best idea ever, yet nobody could code it is game.
