This skill may very well have use in a solo monk build. It is interesting to note that Reversal of Damage will trigger before just about every enchantment, Protective Spirit included. So if the enemy hit you for 55 damage that is the ammount they will take dispite what kind of damage you will recieve.
I used this in my Giant farming monk build and it worked great as it supplimented SoJ.
