All I know is I hope that someday we get to go on an adventure with the "spiritual successors" of Venat, Hades, and Hythlodaeus. I vastly preferred the interactions we had together with them all compared to the time I've spent with the other Scions-besides Estinien as the most recent addition, who I've always generally accepted.
The scions are basically each other's yes men for the most part. There is hardly any bickering besides an occasional stern single line of dialogue from Y'shtola whenever Urianger tries being sneaky or something. Thancred's storyline is stale, and Alphinaud being our obligatory diplomat has gotten so old. How about we get someone with Hades' personality to tell someone like G'raha or Aymeric off when they start going off on their grandoise heroic sacrifice ideas? Alisae at least straight up told Ryne off at one point towards the end of the 5.0 MSQ when there was no gurantee we wouldn't become a sin eater. Ironically, I think I would have preferred to keep Ryne in the party instead of G'raha because I feel there were more opputinities for her to grow bolder and show us what she's made of, as opposed to another "wise" personality.
Overall though, moments like those are so few and far between. Elpis however was a breath of fresh air to me-Contrast the behaviour of the scions with Venat's teasing of Hades and with Hythlodaeus...being Hythlodaeus, it's clear which group provides more actual variety with a smaller amount of characters. They remind me of my favorite party composition from Dragon Age: the myriad interactions between Alistair the knight, Morrigan our witch, and Leliana our faith-driven rogue. Anyone whose played with that party knows how entertaining it was to watch them interact with each other, please give us more of that instead of stoic nodding and "yes, we believe in you!" dialogue from our party.
