What would have happened if...Anakin did not slice Mace's hand of but parried Mace's strike.Ya people will easily say Mace owns he will win.Cuz Anakin is a whiny b1tch and Mace is b@das$.And when Mace beated Anakin he would again have to fight Sidious,cuz as we could see in the movies he still had enough power left.
