Hello Blizzard
from the start of season 1 in Warwithin I do 8XMythic+ for the weekly Vault and I know that when you open the vault you find 3 random items for your spec
my problem is that one of the 3 items is the same item every week a trinket for City of Threads ( [Oppressive Orator’s Larynx)
this trinket is 100% with every week so my loot is 2 items because this trinket is useless for my spec
there are hundreds of items so why is the same trinket in my vault every week
I am not sure if this is a bug or what but like this is useless to do mythic+ any more if this item will keep shown in my vault every week
This is unfortunately just RNG at work, believe it or not.
If you have a thousand people flip a coin and kick all the people who rolled tails, eventually you will be left with a person that flipped heads 10x in a row or more, which statistically is nigh impossible… but even if you do it with a million people, in the end there will still be that one guy standing there that flipped heads 1000 times.
I´ve gotten Fateweaver in heroic from the delve vault slot literally every week on my mage for the past 6 resets… that thing has a sub 1% drop chance, and I already have one… It just the way things go sometimes… I´m just glad I´m only running delves to help others and level brann, and not because I actually want anything from there anymore.
So, I feel you, but all you can do is keep pushing, it´s unfortunately not a bug but just crappy luck, happens to all of us eventually.
