I think it's safe to say that creatures were way too powerful after the rebuild changes went live. Unfortunately, they were one of the last changes we made and probably got the least attention in pre-release testing.
Thank you for all of your feedback. It has helped us become aware of imbalances and we've worked to fix them, particularly reducing the damage capabilities of all creatuers. Please provide more feedback regarding the 1 PM EST Nov 2nd changes when you can to let me know if it's done the trick or more tweaking is required.
