These are two items I’ve kind of always wanted to see added as permanent fixtures.
The first is pretty obvious; the “WoW” tabard. We get the visual for it when the anniversary rolls around, but it would just be kind of a fun item to be able to keep around. It would perfectly suit both retail and Classic WoW, as well.
In fact, I would personally dig maybe it an “Artifact/Heirloom” and maybe display your own personal anniversary? Like “Est. 2004” if that’s the year you started, etc? That would make for a pretty cool cosmetic, imo.
The second item are the old “GM robes” from back in the day. To my knowledge, GM’s don’t really appear in-game anymore, so the item is effectively nonexistent. It’s just a pretty standard looking robe, but uses a black-and-blue color scheme not available anywhere else in the game, and had a matching hood if I’m not mistaken?
It’s cool to see the Blizzard service rewards immortalized in the game (although sorta surprised those are being shared with players), but seems like this would fit much the same kind of celebration.
Just my two cents!
