I feel Astarion was one of the bigger but not so obvious victims of whatever led Larian to basically flatten everything and make it less moody and more heroic. He isn't quite Gale where he's a very different character, but it feels like they basically removed Astarion's edge and made him duller than he was. It's a shame. Could've been a victim of the removal of the upper city and whatever role Cazador was going to play there.
