The low level roulette seems fairly partial to a select few in my experience. Most times I get Halatali or Satasha, I have gotten Tamtara and Ifrit maybe 3 times since the patch and I do it daily for the rewards, and some days I do the roulette more than once or twice. It's a sad day when I'm dying to see Aurum Vale and I hate that place with a deep, burning passion.
