Yeah they reeeeaaally need to do this. Darkspear have a ton of characters they could flesh out - Vanira, Bwemba, Zen’tabra, Gadrin, Volrath - but just never have. They’re honestly worse off in the “nobody matters outside their leader” department than the Forsaken are, which is impressive. The closest thing was Gadrin having a bit role in the BfA Vol’jin quests.
I’m unfortunately not very optimistic about the Darkspear’s future after the Zandalari stole a lot of their stuff in BfA, like Bwonsamdi being their most important loa, and how SotH talked about the Darkspear being the true inheritor of the loas’ wills while the Zandalari lost their way, but then BfA had loa all over Zandalar. It feels like the tribe’s role has been completely usurped.
