I think most can agree that the Power Outage is the most fun and changes gameplay to be much more interesting with the Daemonhost threats everywhere, but for whatever reason when this event occurs it only lasts a few hours. Otherwise its always the same feeling boring missions with more hordes or specials that lasts for several days and doesn’t add anything or feel any different than non-modified missions.
Give us the power outage global event more, or make the other events more interesting and eventful than just “X% more of Y enemy spawns.”
