Traek Jr. is due to make a re-appearance at some point in time. A dev said it was one of their top priorities after 2.5 bugs settled. However, I was directly told by Slaar that Skoal the Malignant is removed from the game indefinitely, with no plans of him ever coming back.
Man, this post has been one hell of a ride, 5 pages, and maybe 2 have bard song relevant information. Thank you Rymy and any others in the shadows helping out for 2.5 bugs. Also thank everyone else who posted bard/2.5 related bug information here.
