"Raid-boss" type grinder

Hear me out: The grinder is TPS was TOO powerful, but still an awesome feature. So, rather than making a weaker version in Borderlands 3, include it and limit its use. Players can only use it once per day, and they have to pay a price (E.G. 20 eridium or something) to access it, then it’s re-charging or cooling off or whatever, for 24 hours, like raid bosses do.
You can even add a “Guaranteed anointed” option, for extra eridium.
