They got to do something with Elidibus... Like they can't pull another Emet-Selch without feeling like they're re-treading but at this moment unless they do something to change him up, then he can't help but feel like a major downgrade.
I still don't quite get Elidibus' angle. In the early chunks of the story he was in he was working for balance so neither side won out. But after he took Zenos' body he seems to just focus solely on destroying life and killing the WoL.
I originally thought that he was a rogue Ascian doing his own thing and trying to stop the Rejoining, but it doesn't seem like that's the case?
