In no particular order: - That the story may be mediocre; - That the reaction system is not going to be fixed; - That the UI is going to stay the same (I know they said now it's perfect but I still think is terrible); - That all the immersion-breaking features are not going to be tweaked to fit better into the experience (e.g. fast travel); - That the short/long rest stays like it is now, making players miss on core parts of the storyline and the interactions between characters; - That all the homebrew is going to make the game too easy and/or make some classes useless because their core features are now meaningless or completely overpowered.
