So I would like to share a few themes for Crown Crates that I would like to see considered in the near future. All in all my hope is that for a while we see some Crown Crates honor certain gameplay styles in the community.
Three Banners Crown Crate: I would like to see a crown crate dedicated to the people who fight in Cyrodiil. Nice special mounts that change appearance based on your alliance, along with other alliance specific cosmetics.
Zenithar Crown Crate: This has nothing to do with Blackwood. Actually it would be a crown crate dedicated to the Crafting Community of ESO. Mounts would be carrying tons of resources like pack mules. Maybe have a few extra outfits for enchanters, herbalists, and such. Also maybe an emote that shows off a well crafted item.
Flesh Atronach Crown Crate: Lets make some fleshy friends. Please if you do this, add a Flesh Atronach polymorph that is absolutely hideous. It should give an Altmer nightmares.
Dremora Crown Crate: This is just a personal request. I would like to see a crate dedicated to my beloved Dremora. Maybe include a hairstyle that explains why the Dremora we meet are bald in ESO. For mounts I think it should be animated bound armor, but that's just my two cents.
