Eh it's not that bad, it's normal that he's still unsure of things so soon after Cazador.
But it's very obvious that ascended Astarion has more things to say overall. He also gets gameplay benefits and an ending that doesn't turn him into a joke.
It's not really that he's unsure of things post Cazador if you go down the spawn route that's the issue, the issue is the lack of ability to properly affirm his choices and discuss his future.
Definitely agree with that yeah. Unfortunately that's how the entirety of Act 3 is.
