My guild recently started working on Heroic Paragons and I'm trying to understand Fiery Edge damage. I'm aware of how the lines connect with one another, but on our only pull that had Lucid up for a prolonged period of time I was repeatedly getting 2 stacks of the debuff, which seemed to be unhealable (link provided below). During each connection, I had 4 lines connected to me in similar V shapes, one being slightly narrower than the other and had 2 stacks of the debuff, Fiery Edge.
After I died, our disc priest managed to solo heal all of Xaril and half of Kaz'tik before wiping, so I'm certain that it isn't the healing output that was to blame, but rather something that I did incorrectly.
Kaisis is a tank and Seiius is a Windwalker monk (melee dps). I (Isiildur) am a Holy paladin.
