I think we are talking past each other.
In my experience if you play the campaign again on level 50 you will barely get any new good loot.
How much green weapons without anointments do you still use on level 50?
A few levels ago i still had a white jakobs sniper on my Moze. If i use a white weapon on max level i heavily lower my damage output.
This is not the only reason why i don’t like reaching max level.
On 50 i have to use mayhem mode to get a higher difficulty (which i dislike). Before that i can stay underleveled.
