The reason the Slaughter shaft is the pinnacle of difficulty in borderlands 3 is not because of intentional game play design. Bandit Badasses and Bandit Anointed are unbalanced and abuse gameplay and engine mechanics. No other enemy type such as Guardians, Maliwan, or Creatures have mobs that are capable of what Bandits type do.
Bandit types have Badass rocket launchers/snipers with deadly accuracy. They blind you and make it impossible to counter them. That is not a gameplay design mechanic. That is engine abuse. They have NO RELOAD and insane fire rate.
Anoited are capable of doing the same thing. Except They have random immunities that make a high health enemy a chore to deal with. They teleport alot of the time which trivializes position in a game doesn’t even have a cover system.
Maliwan and Creatures and Guardians do not have these enemy types which is why Cistern Slaughter and Slaughter 3000 are balanced endgame challenges RELATIVELY speaking.
Please fix in the next hotfix. These are obvious outliers that are over-performing. If you can nerf guns that are “over-performing” then for the sake of build diversity these enemy types need to be nerfed
