Luck as an armor perk has to go.

Sure, it's kind of a waste in the drop pool since it's pretty much worthless.

Also the way the game is designed having luck currently is mandatory for any end game pve content.

Do what now? Luck only affects the rarity of an item, as in the chance it bumps from white to green/blue/purple/orange (if 600). It has no impact on quantity of drops or gear score of drops.

It is almost entirely worthless for the watermark grind, as well as dungeons since the items that matter are fixed epics unless they hit 600 and are auto-orange. How do you figure it being required?

As someone that has kept up on the watermark grind, found plenty of oranges, and made plenty of money doing so, regular non-gathering Luck could just straight up be deleted from the game with minimal impact.
