Besides the evil-evil path, the more casually chaotic path is also not so very well catered for. All this juicy blackmail material in Act 3 and you can't do anything with it. It would be so nice if you could give it to the Guild or to Wyll - if you want to build him up as a politician so he maybe owes you a few favours - or use it for yourself, build a second newspaper to sully Gortash's image, fun stuff.
