Tomb of Jade and buttons, buttons, buttons
I wanted to share my thoughts on Tomb of Jade and the button requirements of this build. Tomb of Jade is one of those rare DDO abilities that has almost no utility in heroics but becomes extremely good in epics. There isn't much need to encase a mob during the heroic blitz. However, in epics, stopping champions and reapers has more priority. Tomb of Jade also benefits from strikethrough so you can encase multiple reapers, champions, elementals, etc, with one hit. Tomb of Jade is so good in epics that it would be hard to play a monk without it once you've used it. The ramifications of this are that you'll need to work in 22 APs into Shintao during character building.
Monk has so many good abilities now, the hotbar and mouse begin to get overloaded. Unlike spell casting, where spells have cooldowns and you can get to them on other bars, melee combat is fluid, and especially as a monk, very fast. Fitting everything into an accessible area is difficult. Therefore, even with the changes making monk less button intensive, it is still a high ceiling build. Here is what I consider needed at L22: Quick Strike, Shadows Cannot Exist Without Light, Whirlwind Attack, Hand of Harm, Void Strike, Cauldron, Abundant Step, Quivering Palm, Reaper's Strike, Clear Mind, Haste Boost, Spring Attack, Two Jade Strikes, Two Katas of Ice. My mouse has reachable buttons (several more that are too awkward to get to in a fluid manner) where I put WWA, Quick Cutter, and Shadows. The rest goes on hot bar 1 thru 0. But we have 13 abilities for 10 slots. And this doesn't account for a heal button like Renewal. Now your mouse might hold more, and you might be able to use tool bars to greater effect in melee, but for me, if a melee button isn't on the top 10, then that means it's more than likely not going to be used often. Because of this, I've more or less banished the Katas and Jade Strike. But Jade Strike does have a debuff, so it's going to be useful in raids. Which means I will likely put Reaper's Strike above the main 10. Even so, that means I won't easily be able to hit haste boost and Reaper's strike (although again, in raids where Jade Strike is more useful, some will be run on LH where I won't have Reaper's Strike anyway). How has your use of Kata gone? The upgraded dancing part is another form of CC, but I don't know if I will ever actually use it.
Cauldron is far more useful in epics than heroics, but I can see how you trigger it a lot. It's certainly doable. I use it with large mob concentrations. Usually, my pattern of engagement is Spring attack into a mob, then quick cutter then WWA. This kills the initial group. If more mobs are drawn in and attacking me, I drop cauldron.
Weapon wise I went with Elemental Bloom from 6 to 18, then am using Bone Breaker, and I'll switch to Sireth at 23 up to 30. I'm very pleased with all three of these DPS staffs.
