In my opinion there is nothing wrong with the scions but they need to stop putting them ALL front and centre every expansion and they need to start transitioning some of the scions who’s arcs are complete from the front lines to the back lines
Alphinaud and alisaie didn’t get nearly enough development but the story idea of “we are going along as emissaries because we want to learn more to help garlemald” was IMO a good direction for the twins in terms of their characterisation. Y’shtola stepping back to finally fully focus on her shard research is another good example they seem afraid to commit to
The only member of the party that HAS to be there at any one time is the WOL, they can bring in scions for limited stints now and then as well as focus on newer characters, krile, erenville and Otis for the short time we had him were examples of what they could do there
They also need to stop being so afraid of using present NPC’s in duty support, there is literally zero reason why oblivion couldn’t form the majority of people you do origenics with
