Skoll Shorties

You'd think that Sylvanas viewing Talanji as having betrayed her she would have been a target & have her involved, especially w/ Bwonsamdi in Ardenweald. Would be nice to see one of the few good additions from BfA have a role beyond it but nope we need more Thrall lol #Warcraft

They probably chose Thrall because has had several connections with dead characters. At least this reasoning is a decent one. I do agree though that they should've included Talanji in the mix. Hopefully, she'll show up later on.

So have so many other characters who are actually part of the current storyline and not constantly dragged back into the story the second before an arc ends for nostalgia. Vol'jin and Bwonsamdi, who I assume you also mean, have literally nothing to do with anything about him.
