That's one thing they got right in Anthem.
If I'm over levelled in Anthem, I can go in and beat the crap out of anything. So if I'm feeling laid back and just want to get my Casual on, i can do that.
If i want a challenge or better loot (well better is like more higher level, not really "better"), I can pick a harder difficulty.
It's all about Choice - which is the exact opposite of how Bungle operates. "You can play any way you want, as long as it's our way".
