Anyway, looking at the Durumu kill:
Healing Sphere is your highest heal at 26.6% of your healing? O.o You're missing out on a lot of Chi generation to cast Uplift and Enveloping Mist. I know there are some Healing Sphere proponents around, but I say try a more traditional Soothing => Enveloping/Uplift (ReM on CD) rotation. Save Healing Sphere for when you need burst tank healing.
Also only 20% on ReM? 42 casts out of 71 possible casts. Ouch. Get a Weak Aura to monitor your ReM CD. (Also cast one on the tank during the pull).
Also, Chi Burst is not working for you on that fight. On a fight like that, it's going to suffer in 10 man, where the raid splits into 3 groups (beams) during the highest raid damage phase. Better to take Zen Sphere here. (If you switch to 25 man, it's fantastic here, just not on 10).
Also you're barely using Expel Harm. It's cheap, guaranteed Chi and potentially some good self healing.
