Suggestion: Dynamic minimum item level and unlocked instances on roulette

[Brightamethyst]

I'm really sad to see that people baits the roulette system by registering on those roulette naked to lower their item level.

While that definitely happens, it's not the main reason you see Crystal Tower 90% of the time.

Quite simply, Crystal Tower is the lowest common denominator. It's the lowest level and the only one you're required to do. To get Nier in roulette all 24 people have to be level 80+ and have the raid unlocked. Meanwhile it only takes a single person under level 60 or with no other raids unlocked to force the other 23 people into CT.
