Antitower question

[Galborion]

I think many people are overgeared for it since I never had to mark stuff and most of the time I pull 2 packs at once with some CDs on the bigger pulls. Though I do have a question of my own about The Antitower. Is the Expert Roulette purposefully designed to give you that instance more than the other one?

It is just your luck. I personally almost always get the other one. Since update I had like 5x antitower and like 40x lost city...
