I like that Astarion is not connected to the plot. Sometimes I just grab him, leave or kill everyone else, and we go on an adventure to solve our personal problems and kinda accidentally save the city in the process. Or would save the city, if I ever got through Act 3. On the other hand, having the Upper City and some quest for him to charm and lie his way through would have been sweet.
Well, I would love to see more quests that are meant for Astarion (or Wyll and Karlach). And of course, I would love to see the upper city. I think that part of the unbalance with the companions is because many of the quests and content were left for the upper city and when it was cut, we lost all that content. But that is why I think all companions should have had a similar amount of content in all 3 acts.
I would have liked to see more Astarion on his element. Or discovering himself.
