I have been playing on Xbox with my brother. The heroic strikes really aren't anything impressive. Heroic doesn't mean what it does in say World of Warcraft. The enemies don't hit harder, there is just more of them. Me and my brother 2 manned the weekly heroic. I really want to write up a review of both destiny and xbox one, maybe I will do that today. I have some serious issues with xbox one, but destiny seems solid aside from them releasing a % of the game at a time rather than the entire game and then additional new content as DLC. I will talk more about it later.
