Damage comparison
The damage numbers do contain personal debuffs, which in this case is limited to Shadow Loss from Shadow Strike for the pure Monk. The numbers also include Favored Enemy damage, which is highly relevant with the Horizon Walker capstone.
The four different modes are:
Epic - All boosts including epic moment
Full - All boosts except epic moment and Diversion
Partial - Ranged Power only
None - Just auto attacking
The gearset is truly a work of art, especially the ability to swap in spell absorb cloaks with minimal loss. The gear is optimized for high level reaper play including raids. If you're going to solo, then the gear will be different as you'll want the new Raptor Tooth Necklace and Soulrazor for a net +21 damage.
Crusade is actually the highest damage epic strike for pure monk, but losing Shadowdancer or Grandmaster of Flowers for it is an overall DPS loss.
The favored enemy calculations don't show the complete picture: The Ranger split covers all raid bosses except for Hound of Xoriat. The pure version only covers Evil Outsiders.
