I read here https://pso2.arks-visiphone.com/wiki/Mission_Pass that:
"ARKS Missions will now have a new category called [Tier Missions], which allows players to complete various tasks each week to earn a set amount of [Stars]. Gathering enough Stars unlocks Tiers in the Mission Pass sheet. From here, you'll have the option of collecting rewards for each Tier you've unlocked."
So, doing ark missions can i advance these tiers?
