I guess I can see Tempest Rush as a utility snare with that rune, and it being quite good at it-- and I had no idea it prevented you from being snared as well. However it still leaves you with zero decent spirit spenders for damage purposes.
Realistically, then, I think you're going to have to swap out one of your other abilities. Obviously you want a mantra, so you're left to jettison the worst of Serenity, IS, and BoH.
Serenity runed for Tranquility is absolutely beastly for multiplayer, so that's going to stay. You then have Breath of Heaven versus Inner Sanctuary runed for healing... obviously one of these two is going to be the far more viable healing option, and while IS is really cool in theory, it's also tiny, so I don't see it being useful often for its original purpose (at least not without a very concentrated choke).
MoE with Divine Protection is actually a really good option I forgot about, I don't much like Dodge when I could get flat damage reduction instead though, which is why I'd been planning on MoC-- but with those values nerfed I might reevaluate. I'm still not sure if the clutch ability from this outweighs say the armor rune though, especially with Serenity (Tranquility) available.
Your rune choice for BoH isn't necessarily bad, but I'm not sure it's something I'd use-- it's a great opportunity to pick up free damage via Blazing Wrath, but it seems like you're really dead set against doing any damage at all :P I guess it largely depends on what enemies are actually affected by the fear.
I really don't like Sixth Sense as a passive-- 1 it's dodge (not DR), 2 it's only based on a portion of crit, and 3 crit isn't going to be nearly as high as Dex anyway (I'm looking at you, Seize the Initiative!). Near Death Experience also seems super redundant since you already have 2 saves.
Anyway, here's what I would change in your build (and obviously some of it's debatable like the BoH rune-- passives are probably the one thing I'd definitely have changed if anything though):http://us.battle.net/d3/en/calculator/monk#VedUcX!aXY!ZbZbYb
