I really hope they change the lv66 trait to Tornado Kick mastery, make it that under different fists it will have different uses.
Fist of fire : Just a normal nuke that doesn't consume your GL stacks.
Fist of earth : Do half the damage and save your stacks upon recast you gain all of your stack back ( Longer CD )
Fist of wind : Tornado Kick is basically a ranged ability and refresh the duration of GL
In a way it fit the niche of each fists and is a big improvement over the thing that we have now, but alas we got Tackles
