As far as PvP goes, it's whatever. Its PvP. But for the PvE stuff I think that, despite it's failures, Anthem had a cool difficulty tier list. The harder the difficulty, the wider the loot pool and more loot that is rewarded. If a solo player wants to grind out an activity solo, they can but they will have a more limited loot pool and drop rate. Higher difficulty, more players more rewarding. Even if Anthem wasn't exactly this it's still a great idea IMO.
