I wonder if lower player Frontlines could make queue pops all night. On Aether for instance, queues typically die a little after midnight PST, usually later in the weekends and especially if it's Onsal. Maybe there's not enough people past that for 72-man but maybe 24 could keep it going ?

For Crystalline Conflict games can go pretty late (maybe 2-3 am), but it's called degen hours for a reason....
