N/Me for B/P Tombs???

I've been running my MM in the Tombs with B/P groups and got to thinking about what pisses me off the most...Cry of Frustration!!! When the group comes up against multiple Scythe of Chaos I always get targetted with the Cries. Sometimes up to 3 in a row, then I'm at low energy. So trying to find a way around this I came to the conclusion that going Mesmer secondary might be the answer. If you're monk and Orders aren't retarded I don't see much of a problem. The one thing I don't like is losing Rebirth. The build I'm about to try goes something like this:

Death - 16
SR - 10
Inspiration - 9
Blood - 4 (leftover)

Horrors
Fiends
V. Sac.
BotM
Deathly Swarm
Mantra of Concentration
<<>>
Res Sig.

I can't figure out what to put in the open slot, maybe Inspired/Shatter Hex. Feedback would be much appreciated on what to put there or if this is even a good idea. I usually bring Heal Other just to help out in crunch times. Any ideas?

Mantra of Resolve is probably better, Concentration only prevents the next time you would be interupted. Resolve Blocks all for X amount of time but you loose 5-10 energy when it ends(20 second recharge time!)

Yes, Mantra of Resolve is a much better choice here. Offering of Blood also helps.

I run a N/E MM in tombs for a constant verata, and I don't find the interrupts much of a problem. As long as you and the group have half decent positioning, you won't even be targeted most of the time. Honestly, I don't think trading a constant verata for the chance that you'll get one extra cast of as being worth it
