Right now Monks are one of the worst (if not THE worst) class on utility.
BrMs have the least utility out of all the tanks. Looks like Ox statue is the only useful utility ability they get.
Suggestion: Zen Meditation is pure shit right now, especially for a 5m CD ability. Turn it into a raid ability. Bake in the PvP talent 'Guided Meditation' as default with it. This will give BrMs enough utility to be useful and will warrant its 5m CD.
MW has Life Cocoon (I'll count it as utility since it also increases everyone's HoT on the target) and Revival.
Suggestion: Make Mana Tea baseline and have the talent turn Mana Tea into Innervate, making it possible for you to give tea to raid members.
WW has no utility, whatsoever. I don't play WW, so don't know what to suggest. Maybe a raid wide damage mitigation ability.
