This killed me as well. They deserved one last hurrah together, and I swore episode 4 was setting us up for it with the Eir and Snaff reveal. I didn’t expect them to get the final blow, but I honestly felt like it should have been Eir and Snaff as ghosts, with Loghan, Rytlock, Caith and... Lol who am I kidding, Zojja evaporated into the sun after Mordy. Gwen though? I like Gwen a lot, but... why? Why though? Why her and not letting the team that tried and failed get round two? I was very much like “oh man! They got a VO for Snaff! There must be something coming!” Oh well, maybe they were at the topside battle and we had no idea, and DE will talk about it a bit, considering we have no idea where ghosts and dead folk go now that the Mists have been folded in half.
