Do what are you saying about those recent changes to MW spec?
IMHO Chi Brew seems very interesting, it won't be as strong as of now where you could preReM whole raid (I am 10 man raider) and then use 4 Uplifts in a row - mighty strong.Chi Brew now restores 2 Chi, has a 45-second cooldown (down from 1.5 minutes), and generate stacks of Brew/Teas based on the Monk's specialization.
I was thinking about going a little bit more mastery in 5.4 (due to 2pT16) but now it seems we are forced to have more mana-regen stats...Mana Tea now restores 2% of maximum mana per stack (down from 4%).
