I commented on here already, but I was thinking. It would be great if we had the same interaction with housing here that we had with Skyrim. To take it further, why not give us a quest like in Skyrim where we can earn land and build our own house. This could be a one off quest that could be picked up in any area we would want to build a house in.
As an alchemist on my main, I'd love to have the ability to plant things like Nirnroot, Columbine, Lady's Smock, etc.
However...I'd accept a challenge. Make the cultivation time a week or longer, make the plants have requirements like sunlight, water, earth instead of stone, fertilizer, etc. That way we're not destroying the alchemy market for Guild Stores; it'll still be faster to farm the nodes, or buy them from stores, but perhaps make the cultivated crops yield more?
