Very common comp because of the low population, frequently seen mainly during HA bonus weeks/zaishen quests/the anniversary event. The spike's solid and the hench builds are good for the most part.
Of course it's seriously outclassed by player comps when the objectives get more complicated (like conquest or most HoH modes), and players are inherently better at many things including positioning and syncing things like SoC for Ghostly channel or Rez skills. It's not impossible to win though if the enemy players have a suboptimal comp or aren't that experienced, I've won HoH with this several times (and not against bots).
For its purpose, farming bot henchways, the ideal henchway team. Also works against bad (that is: most) player teams unless they run a henchwayfarmway themselves.
