There are more than enough players that would go for world bosses, destiny may be pretty casual, but there are plenty of people who play a lot and play to win. As for Patrols, simple starting with making separate levels of Patrol could make them more relevant, with very little work, as the would only need to up the levels of the enemies, while leaving everything else pretty much alone. Not to mention doing it the way i outlined makes certain things relevant again, like blades of Crota. I welcome your feedback, but the point of this is to make things relevant again, and make them more relevant continuing in the future, as out levels grow patrol will be less and less useful aside from bounties.
