Modified Onyx Annulet still useful beginning today?

To what percentage will the Onyx Annulet be reduce & which type of player may be most affected, a dungeon/raid player vs the open worldly Boss/weekly quest semi-solo casual player? I am prepared to replace it, should it become useless in what I personally do in the game. What say you?

Personally, kinda hope it dies. I mean it was fun in the beginning, but being able to super customize an OP ring for any content you wanna run - higher heals, higher burst, whatever - just seems eh. I know a lot love it, and I feel bad that it’s gotta be broken to the extent it is, but I think it just needs to finally flop.
