This is incorrect. I made a video showing and explaining that the arrow behaves differently depending on the distance you are when the arrow first pierces. Best results were between 20 to 40 yards, not on top of the mobs, and buriza had no effect on this. Not the best person to be pulling DH info from.
Regardless, point is that an easy fix could have applied to GoD6 HA instead of hard capping it at 4 no matter what you do, making high GR’s a very frustrating experience.
I’m sure you’d have the entire monk community up in arms if they increased earth allies damage a little, but it can only hit 5 mobs, all to just fix the missile dampening issue.
