ok, so Single boxing right now, with level 12 guild. avg Gear iLevel is 350 per toon. We clear trash to Halfus every night. 6 days a week, seeing ~ 6-10 epics per week. Drop rate is 15.2% based upon some comments from official forums. Selling these epics has been challenging. We are to the point where we just shard them. Shards sell faster.
