EX Roulette is Rigged

[Artiste]

I do the EX Roulette daily for my alexandrite without fail. 7 times in a row I have gotten Satasha.

What's the problem ? You cant do Sastasha ?

It's no, it's not complete RNG, you can get into a donjon with players that are not queuing with expert roulette.
You can for exemple, if you're a healer, and a tank and 2 DPS are waiting for a healer for Sastasha, you get with them in Sastasha (that's just an exemple to show how it work)
