Is Overseer Agent "Skyking Molad" even dropping at all? This agent is supposed to drop from Season 3 Celestial (green) Overseer Mission rewards. I have been running them intensively and have not seen him.
I may just be a victim of the RNG, but it has been a looong wait thus far! This is the Skyking Molad with the "Courageous, Stalwart" traits, not Skylord Stormtalon.
