Currently our level 75 talent Dampen Harm is bugged whereas the charges will be consumed by Stagger, and by hits that are nowhere near close enough to 20% our health. I am kindly requesting that every monk regardless of their spec submit bug reports on this issue. This needs to be addressed but thus far we haven't gotten a single response from Blizzard on this because I am pretty sure it hasn't been mentioned enough or prominent enough in their eyes.
Sample from someone else:
9k ticks from stagger = 20% of total health?
