In Shadowlands, players will be able to quest through four new zones ruled by ancient and powerful Covenants. Upon reaching the max level of 60, players will be able to join one of these Covenants as they continue to explore the Warcraft universe’s afterlife and the many mysteries and adventures that it holds.
This is correct. You’ll get to experience a taste of each zone and their associated Covenants as you level. You’ll even be able to test drive their abilities as you play through. That should give you a better idea of which Covenant is right for you.
Spawned rares and rare elites are summoned by a Covenant member (within the Anima focused areas), but anyone can take part in killing them for loot.
Beyond that, daily quests, treasures, and the world quest you can get from conducting Anima to a specific area are only for you.
That said, this is only a small portion of the overall activities that are available to you and ultimately, you should choose to play in the Covenant you will enjoy most.
Lots of discussions are happening. This is why testing and feedback is so important. I can’t address your specific point, but can at least give you that there’s still a lot of work being done on this end of things.
