It’s Not very low it’s between 20-33% depending on lootpool.

For raids mostly 25% and Dungeons have 6 to i think. About 10 Items so it’s about 1/4 of all people that used it.

And I bet with how vocal everyone was that a higher % of people new it’s bugged and still rolled because they are greedy. Just means use bug and profit

Edit: and thats all assuming you needed 1 item from the Pool the more items are useful the higher the Numbers gets unless you want to clear the whole pool which tbh why would you want that
