Completion of the quest “Disturbance Detected - Ulduar” provides a chest that has a tool tip saying it “Contains a piece of Hero equipment for your Loot Specialization and a chance for additional curiosities lost to time”
However, according to two different GMs, this is inaccurate text and “it is possible that you may receive pets instead of gear from the cache, which is the part that is working as intended.”
While I would prefer that the Cache always give Hero gear, then if this is not possible,
I feel that the tooltip should line up more closely with the actual results of an item, and the text on this should be changed to “or” if that is how it is intended.
