Yeah eminence healing doesnt seem to work too well for me right now, but soothing mists for chi and uplift at damage spikes is working quite well. Do you still like to use SCK much?
I've never really had to use cocoon in the 25 man environment but I can see where it would help for Vizier in 10 man. What fights are you using glyph of roll on? I've never had the need for it in 25 man except for Elegon adds when first learning. How about SCK glyph?
I do like chi brew when I've learned the fight better. It is nice sometimes to have that extra mana and 1 chi from ascension to pool though.
I havent picked up my 2 pc yet but I will definitely be going for the higher haste break point when I do. I've also been noticing I have a lot of mana with spirit/crit gems so I will probably be gemming mostly int/crit to test. Have you tested different gem combinations?
As for the logs, it looks like a bunch of them have expired so I wasnt able to really dive into some of the heroic attempts you've done. From the few I've seen your survivability looks good and I see good use of cooldowns (TFT, diffuse magic, zen med, mana tea, fort brew and cocoon).
