Can't complete 'Let's Play Some Ranked' mission.

Title. Obviously this is due to ranked queues not being on atm, but then why even have the mission be available? Gonna miss out on the 2nd chest and key due to it, and it's not like playing 3 ranked games is any difficult. Why even lock the quest behind ranked anyway, when a decent part of the community can't play ranked (underleveled) or don't want to. (either due to not liking ranked, or not wanting to risk losing LP, I guess)
