I understand that you are talking about the DnD, but I just want to say that this is a simple fight. I killed gnolls with first try, and boss too. This fight is much easier if compared it with Spider fight, which took me a really long time, just because I needed to understand 'web' mechanics. Maybe it shows the difference between DnD players and not DnD players. Your perception of the game can influence your battle strategy. Hmm. Because players who don't know DnD rules play with what they have and consider it normal.
I don't mind if Larian make game "more DnD".
