They're not in the roulette because they are the savage of ARR. You would be synced to lv 50 and most people these days don't even know how to do a lot of the mechanics. Turn 3 is a jumping puzzle. They also have adds that for the most part you can't skip as they are on the way to the boss. Turn 8's map can be a bit hard to get around. If you think trying to get someone to adapt and take a different spot for a mechanic is hard now and that the responsibility for mechanics in coils would be easier then jokes on you. Even when Final Coils was fresh and people were trying to play catch up trying to get people to learn how to do the towers in T8, do renards in T7, to know the timing for how to cheese divebombs in T5. Or you know remember if it's Ice in this time with a bunch of randoms you have a lot more faith than me. People still get eaten by carbuncle, knocked off the arena while fighting Kefka and not deal with Faust in A9.
