Are roulettes broken? especially leveling and trial roulette

[BaconBits]

I've been getting a good mix in leveling and trials. Even the 50/60/70/80 roulette (which really needs a better name.....) has given me some odd choices. Can't remember the last time I saw Copperbell Hard.

Alliance roulette, on the other hand, keeps throwing me into Copied Factory.

Normally I'd prefer Copied Factory over anything related to Crystal Tower, but I keep getting thrown into clown shows where fights are dragging on longer than they did on patch day, and people managing to wipe to the add phase of Engels and 9S because they won't separate them.
