To add something to the topic: I would like to see Edér, Xoti and Aloth.
Pallegina has in my opinon an complet arc (depending on her ending) and has not necessarily return in PoE 3.
Edér has a complete arc too but he is just that kind of guy I think who helps if a friend calls for aid.
Xoti has to return because of a uncoplete arc with the watcher. Romanced or not.
Aloth as the leader of the leaden key has to return for story reasons.
I realy hope that there will be a part 3. Since Deadfire it has always felt like a three part story like Mass Effect.
But hopefully with better ending, what should not be this hard
I had hoped for ME3 that there will be a happy, bitter sweet and a bad ending.
And these are also my hopes for PoE 3.
I would rather still wait for a while and have a legendary story than to wait and have the same dissapointment like in ME3.
