4v4 Feast Queues are fast on Chaos atm, even for ranged. You'll have the most luck queueing during prime time, with queue times ranging from <5 min to up to 10-15 minutes. Depends on the day.

Feast queues are either popping, or they're not. During the day they typically won't pop at all, but once they do start then the queues usually last throughout the night.
