I'd say my biggest fears are: - Class restrictions on Spells not making it in and Gale and wizards learning all spells under the sun; - Reactions being lacklustre in execution - Acts 2 and 3 getting smaller than act 1 (not recall how it was in DOS II, but wasn't act 1 the biggest? lol); - no mod support, dungeonmaster mode or dungeon designer a la Solasta; - Larian not realising the expansion potential and doing their usual enhanced edition before moving on to other projects.
