What happened to Uber Lab?

I have more than 420 open chests at Uber Lab in this league. It is disappointing to see how much the rewards have been reduced by opening the chests, it even looks like Uber lab from the same reward as Merciless or Cruel Lab.

What's the use of running 40-50 Uber Lab a day with double enchantment prophecies and in the game there are more than 300 active gems and with 2 to 3 variations for these 300.

When the server resets, the enchants run on that day are lost and start repeating again. It is impossible to run so many enchantments a day because of a lot of garbage that exists.

Remove the access key for Uber Lab or add an Betrayal-type system, where you can see a random list from which you can choose an enchantment from the list, also let all the game's enchantments run on the item without repeating after resetting the server.
