The development team behind Shadowlands has already mentioned Kael’thas and Uther, so it seems like those two characters are confirmed. Perhaps the old man could talk Thrall into stepping back into the leadership position? With Thrall coming back into the main narrative at the end of BfA, there could be the opportunity for a very emotional moment between Durotan and his son. At a time when the Horde needs new direction, a chat with the leader of the Frostwolf Clan could help set the faction back on the right path.
