When I zoned into the new scarlet monastery dungeon on the priest I am leveling my adding raid achievement listed my incomplete achieves for this dungeon. After reading the three achieves I noticed that the one did not state heroic difficulty was required, so my group tried it and on the first boss we got the achievement Empowered Spiritualist. Not exactly an "exploit" but I guess it is because this was intended to be gotten in pans aria content. Probably something blizzard overlooked. Btw very easy achieve to solo at 85.
