Going to just kind of skip myself into this thread.
In response to the above, I agree that the bot being detected is less likely and that the behavior is what is being detected. What does HB offer to not LOOK like a bot, especially while questing? If the popular profiles (bought or free) all use the same move paths and exact quest order, it is very easy to notice a bot heatmap on blizzards end... they honestly very likely have HB accounts themselves and can literally just trace it out searching for any toon that did every single quest in order X with no variation...
How are you supposed to work in the variation? By hand? Is there an easy way to change behavior at all?
