Slane: I didn't mind him only having a walk-on part, though I guess "Dragon Knights have their own business to attend to" isn't very convincing in the face of the rather serious situation.
Butter: even though I ended up romancing Sebille in the end, that was terribly sad. Typically Larian to have that sort of poignant moment, I suppose, but I wish it didn't have to be that way.
Dallis: I didn't get right to the end, but her intermittent appearances did make her seem like the classic pantomime villain; pity, as she has the background to be so much more.
Lucian: this kinda bothers me a lot. I managed to get used to my D1 character being a dude but I'm not so sure about her also going on to be thoroughly unprincipled.
Romance endings: I guess I don't feel so bad about typically having a "meh" moment at the final hurdle as I so often do, but it'd be nice if they fixed them.
I guess they realised they had to get it out there eventually, but pretty much everything from the Nameless Isle and particularly Arx onwards does feel a little incomplete.
