Arah - Seer Path
Im wondering this too.
Until I see some proof that this boss got fixed I will not set foot in Arah.
I guess I’m the person you spoke with, we have killed him previously with no extra sparks, and our kill tonight was with no extra as well.
The encounter is longer (added an extra 3-5 minutes to the encounter) when you don’t receive the extra spark. However it is still very much doable, just more annoying.
