Everyone loved the fact you could build homes in previous games. Why not have it to where you can purchase land in ESO, even have it as a pocket realm. Guild leaders can purchase land and spend crowns to build a guild hall that suits their guild, from non vamp n ww, to everyone else having something that tailors to their guild. Many RP guilds are plagued by players whom troll, so why not have it set to where you have to be wearing your guild tabard to teleport to your guild hall?
Homes, have to spend crowns to purchase land, and use crowns for the building materials.... Have it set to where you must be grouped to enter someone's home.
This could also be a perk for ESO + Plus membership, get the land for free but still have to spend crowns for the home purchase.
