Darkened Arathi Tabard Question

Hi all. Hoping someone can help me with how I go about getting the Tabard for the Darkened Arathi set.

Apparently it drops from a specific set of chests in Hallowfall called Captain Lancekat’s Discretionary Funds." my wife got the Tabard, and I did not. My attempt to loot it again after a reset gave nothing and wowhead comments say it is 1 loot attempt per character.

I don’t play alts, am I really put of luck to get this Tabard unless I keep potting the same chest on other characters?
