As the title suggest it seems Shadowlands is foreshadowing a break from the norm and a new neutral faction would be part of WoW but seems to be an inverse of how Pandaren pick a faction.
With the addition of Shadowlands, the Covenant and all the "potential allied race" as addition to the existing Horde/Alliance: Ven'thyr, Bastion, Ardenweald and perhaps Maldraxxus, they might be the core races for this potential 3rd faction.
What are your thoughts? Do you approve on finally having a 3rd faction and break the norms of having just the Horde or Alliance?
