So fellow monks.. are you remembering to do your daily quest before a raid? I have to be honest and say i didnt remember it untill a few days ago when my HS was on CD and i was like "oh yea, i can port to kun-lai summit" and i noticed the daily.. and wow.. 3000 mastery for 1 hour, persists through death AND you are right next to the raid-entrance. To make matters even better, the buff still seems to bug out quite often, giving you the 3k mastery for much longer than 1 hour.
With this buff and reforged to mastery i can pull around 25% chance of spawning a health orb, pretty neat
