If you have 3 hero monks who are properly setup, you honestly don't need selfhealing. If you're the type who doesnt trust your monks, or pug's with bad monks, Critical Defenses is all you really need.
The trouble is with your build is that it's reliant on Enchants for survivability... And every mob and their dog in FoW carries Shatter. Personally, I'd either run a Deadly Arts spiker-type to stay out of melee, or I'd bring Death's Retreat/Return as a panic button.
That, or bring a prot monk. Prot rocks. Of course, jonny-scrub wammo still screams for 3 healers...
