Bug description:
The title of the container says that it "rewards a ring or trinket for your loot specialization", but unfortunately it awards trinkets only. This bug has been here for ages, I've completed Tortollan's emissary quest mutlitple times on multiple characters but the outcome was always the same: got a trinket, never got any ring. Possible cause of this bug are missing loot spec tags on rings, that are listed in the container's loot table, which makes them invisible for the loot personification system.

Proof:
Let's check one trinket from the container's list: https://www.wow-freakz.com/item_finder.php?item=165665&&name=ritual-feather-of-unng-ak
You can see, that this item can drop for prot & retri Paladins, all Warriors and all DKs.
If you open any link of any ring from Tortollan Trader's Stock, you can't see any info about availability to any class.
