It appears that some information could be useful to be exposed when healing certain tanks such as Brewmaster Monks. This is more of a problem now that healers have responsibility keeping the tank alive and since monks brewmaster has very low representation healer’s seem to not understand how/when to heal a brew.
For example Brewmasters likely do not require immediate attention if they have a decent SpellCastCount on expel harm. This data, for Ox Stance, does not seem to be parseable in either the combat log nor is it a player aura, making it difficult or impossible to expose in WeakAura’s or Addons. This would be useful for healers to know and make partying with a brewmaster a little less stressful.
Please let me know if I am mistaken and there is a way of obtaining this information about party units other than the player themselves.
