I'd like to be the one constantly buffing the group/grabbing mobs up.
You're using OWE but your resist is all over the place. Now's not a good time to re-gear the monk. Wait for the new patch where single resist can roll 115. A few pieces of max resist on gear + OWE will help greatly. Then, your other pieces can focus on Vit/Dex and DPS.
The way to hold up well in MP10 groups is to survive decently, and that's usually dual LS at >50k life. Spam overawe every 3 secs, and pull in the mobs every 1-2 secs. When you give up the eDPS by not using bells, the CS feels much weaker (1/3 the damage), and chances are you'll want SW:Cyclones to help you sustain your life (synergy with your WKL). CS calculates off the main hand weapon, so you may want to have a very high black damage weapon with ruby inserted.
Some of the ground effect combos are just too much for the squishy monk to tank, so we'd need to DS out to safety. While we're at the perimeter, keep up the overawe spam, but don't pull the mobs out to you. When you've recovered, DS back into the group and continue to pull mobs into the group. Of course, if all the team members ran away due to the intense stacking of ground effects, you can pull the whole area to your new location and start a new core for the AOE group damage.
This method is very group-friendly. You can maintain the 68% party buff throughout the main fights, including Ubers. To spam the spirit spenders that way, you'll probably need APS >2 (2.2 APS will be even better, just in case you do not crit).
Now, if you can afford extremely good gear, you can drop Serenity and put in EP:FIW. The palm marking draws attention like a magnet. Continue to pull in mobs, and they all die in half the time due to the 50% spash upon death. But don't EP on reflect pack or you'll kill yourself 1-shot. If your team has a CM Wiz, you can CS less often (within 16 secs to maintain buff), and plant more strategic EP on about-to-die mobs.
The best place to seek advise will be the monk's forums. There may be other top-geared WKL monks who can map out the exact gear upgrade path for you.
