If you don't have mercenary heroes, change Razah to your third mesmer. That's usually a good idea anyway. Tested with sup dom/ilu rune + major fast cast (=430 health) on the mesmers, it's lovely, I should try dual sup rune next and run protective spirit over spirit bond. Played full prot myself:

Tested in Eastern Frontier. Easily cuts through 4 to 5 Grawl healers simultaneously without balling the grawls, just make sure to put guardian on the right targets. But as you are monk I suppose you should be able to do that!
Use [[Spiritual Pain] over [[Empathy] in Shing Jea; there's less physicals but some annoying spirits.

Have fun with the build.
