I love this revision. Now for some comments.

IMO, sense the void is actually more iconic to the monk than slow fall, as it gives the image of the blindfolded martial arts master.

Now on to pros and cons.

Pros: pretty much everything, dance with the elements is awesome, and better unarmed strike damage and standard action flurry of blows are just icing on the cake.

Cons: 3/4 BAB. I fully believe the monk should get full BAB.
