What games do you consider great in each regard? Just out of curiosity.
Though I found Wyll to be limp lettuce in EA I thought he was better done when he suffered a bit for his choices. Astarion felt flat indeed but I kept waiting for a deeper part of him to come out, but I sent him away after the bite incident as it felt like the only logical thing to do. So idk if he turned out to be more than limp lettuce after that. Liked the other ones, though Laezel died early in my playthrough haha.
In regards to your points:
Story ye act 3.. I feel like it starts with the first emperor encounter though.
Level design some of it is flat but I dont remember every level from every game I play so as long as a good chunk is memorable that is good enough.
Voice acting: I indeed felt the not so special voice acting in act 3 (Ansur)
Writing: At least Jergal doesnt say "motherfucker".
