Every time one of these threads pops up, I'm seeing a bunch of people who are completely missing the point of rolettes. They are not there for you to experience a "variety" of content - you can just select 5 of your favorite alliance raids and do it that way, guaranteed no Sycrus Tower! The roulette is there to throw bodies with a pulse to people waiting in queues for specific duties. And logically, there is a lot more players looking to do Crystal Tower raids than Nier. If you don't like Labyrinth of the Ancients so much, don't queue for the roulette intended to fill Labyrinth of the Ancients runs.
