I didn't know it wasn't on the roulette. I wonder why. But every Tuesday I queue up and can get the item I'm looking for in about 3-4 runs. I got the tank chest as a BLM the other day, it's good to have a list of things to greed on even if its not the main item you are looking for so can farm a bit more efficiently. If you're only down to that one item though it may be harder.
