I figure this build won't last too long in hell or inferno because it depends on you taking some damage, but it's quite fun so far. Some of the skill choices seem a bit wonky and a bit counter to the idea of taking damage to dish out damage, but I don't want to die doing this either. 
While fidding around with this build, I did find out that crippling wave + rising tide actually generates spirit more quickly (in situations where you have a lot of mobs around you) than fists of thunder + quickening because it seems to calculate it on hit rather than use. Since most of the damage comes from the main hand only, it's best with a two hander rather than two quick one handers. The biggest problem I've run into so far is that Ally, Sweeping Wind and Mantra of Retribution will kill the mobs more quickly than I can get in a hit or two with crippling wave so I need a bit more spirit regen currently. When she gets a bit bigger, I'll probably take a peek at some of the higher runes, but that's her build currently.
Edit: Now that she's 54 and in hell, there's been some minor tweaking to the build. I'd like to switch out chant of resonance for something better, but right now her spirit regen is next to nothing and while I can damage things while running, it's nice to get extra spirit while I'm running away and waiting for some cooldowns to come off. I may swap out chant for beacon of Ytar though. I'll have to test and see.
Edit2: And of course after I decide to test Ytar vs resonance, I get shielded mobs and remember WHY I like the little bit of extra spirit regen. Good design by blizzard to not be able to generate spirit off the shielded mobs, but darnit all the same.
Edit3: Her passives change with changes in gear obviously, but her active skills have remained basically the same with some minor rune swapping. Still in act2 hell and doing ok despite being undergeared again.
Edit4: Inferno version of her build.
