I'm personally hoping for the black protodrake to go up. Maybe Tabard of the Argent Dawn as well with the whole Blessed gear that came from the Scourge event. ( Teal judgement pieces )
Seasonal mounts would be a welcoming addition along with BMAH-only spawns. Kinda like we have the Sun-Lute, it'd be a cool way for Blizzard to add missing set pieces into the game. ( Boots and belts for a lot of sets like tier 8 that don't have them )
What item or mounts you want in?
We all know you want a Corrupted Ashbringer.
