I've been wandering about this myself. After all the talk about taking down the bosses so that the rest of the horde will disperse, why is there no option to stealthily kill Dror Ragzlin? On some playthroughs it would make much more sense for my character to choose stealth over genocide.
Also, is it just me, or they've taken out the option to ask Priestess Gut to go somewhere more private? Now she will just offer to bring you there herself. I think if was better the way it was before and it was my preferred course of action for my rogue. They've also taken out the "now you die" dialog option when talking to her after following her to the chapel.
