I think some thing are going to be there in the second act like the Cretché (Laez'el option for a cure is the only one that doesn't find closure in Act 1), the boots quest, the Nightsong one.
What i would like? As other players already said more companions options, more races, classes and subclasses, maybe a skill reset point (not a big player of D 'n D so i don't know if its possible) because I'd find frustrating to start anew to have a character with some particular new subclass or class (or race).
Candlekeep would be a nice touch.
Also a map to explore, more pets to add to the camp, an active crafting system.
But what I miss most is the chance to have more dialogue lines to add more nuances to a character, specially ironic, witty, humoristic, blatantly stupid, or caustic options (for now we have, neutral answer, gentle ones, and harsh ones. No middle lines, no humour, no irony. I miss this, maybe is because I'm playing The Outer worlds too, but I somehow miss the chance to play an istrionic hero who find irony and humour even when immersed in the blood of slaughtered enemies or in a pinch because they pissed of a powerful character).
