Quick someone go explain to Blizzard how to scale damage based on number of players! Tweet them about it or Twat them or whatever you kids do these days. Math is hard. We have been working on Heroic Blackhand for WEEKS. In large part due to the fight not scaling very well when we only have 3 healers due to computers blowing up, vacations, weather, hobo stabbings, or cats being on fire. It's quite a bit harder than any other heroic fight and honestly should probably be toned down just a little and actually made to scale with raid size. Once we had the correct number of healers and 20 people we made short work of him.
We start work on Mythic next week. Still looking for a healer and a few talented DPS. As long as you can deal with Chet making his "O" face as a giant tree like the image above you will probably fit right in...perverts.
