I think it isn't used much currently, and only for those who are seeking a challenge from the olden days of FFXIV's bosses and Alliance Raids.

I would love to see what Crystal Tower was actually like when it was first introduced considering we no longer see all the mechanics anymore, but I think there needs to be a bit of a incentive for players to go along with it so why not add another roulette "Minimum IL"? From there you pick and choose what type Trials or Alliance Raids, I left Dungeons out because most of the time you'll always will see everything those have to offer but over time Alliance Raids and Trials do get their mechanics phased out due to skips with the exception of a few alliance raids I think.

Would you all go for the extra challenge with a roulette like this? I would love to see what Xande was really like when the content was current back then.
