I would love to see a wedding anniversary feature with items including an attire for the couple to choose from.

idea list:
1. Maybe like an evening dress or haute couture.
2. A special ring and head piece would be nice with a special protect buff when executed.
3. Heart icon next to our names displaying our everlasting devotion.
4. Holding hands emote and actually holding hands when we are walking or running together. Whoever initiates the run/walk leads.
5. a japanese serpent double mount

That list is for the first year. Then after the first year the items could include housing items, another special double mount, more attire and special jewelry. I wish i could design it for you ^^.
