Instead of having Haarlep take up time in the house of Hope for a frankly very creepy and weak mic drop on Raphael, focus on the story between the Hearthflame sisters, which is so much more interesting, than a rapey encounter with an incubus, who just pops up and brings nothing to the story at all.

Give a bit more depth to the main antagonists in act 3. I like the idea of Gortash as the ruthless, manipulative politician and cult leader, but he doesn't get enough to do. Same with Orin.
