I absolutely love a lot of the housing aspect. My personal fav has been (and still is) Earthtear Cavern -- although I have collected a bunch of different ones and so have a few I really like --- all have potential and some are extremely convenient to port to and step out of into wherever you are going.
With that said: Consider adding something asap where we can FISH at our own homes (same/similar randomness, maybe make it less frequent or lower chances of getting anything --- for the Homes with enough water of course). The things incorporated into the world should be in the game.
Also we should have of course --- a higher limit. You can do some AMAZING things with all of the places and the current limit. But the potential could be so much more (if of course, this can be done with relatively no noticeable lag impact on the overall game). I imagine that is part of the challenge (and the cost wink wink LOL).
We pay A LOT whether in gold or crowns for these homes. I'm going to go out on a limb and say most of us are just regular working people, some retired, some in school, etc... a few may be swimming in RL gold but that's not what fuels the game. It's the collective, which creates a value more than currency. So throw us all a few Pro-Customer features, will ya?
I like supporting this game. It's one of the few I don't mind because the quality of the game content itself is excellent. So thank you! But, really... let us fish at home. Let us do more.
Make various poses with the seats.. I don't even RP, but sometimes I just want to listen to a podcast and chill in my damn cavern and FISH. LOL Instead, I have a death gauntlet of plants I run through (thank you for those btw, they should be permanently in the store tbh --- everyone should get a go at them lol).
Add some social functions, not just for RPers but people who want to chill. Allow some sort of building while at home maybe, like a slower process to design furniture which grants some sort of xp. There is just so much, it needs to be tweaked. Lastly, allow us to leave directly from our homes OR return to where we were (as long as it wasn't a now-closed instance) --- via getting a prompt AND another option for setting it manually once while staying that way (until changing it ourselves).
Maybe allow us to unlock "portals" to add to our places (with limits if you must lol), that will take us to a place we will be frequenting let's say. This also gives more incentive to actually do more crafting, idling, & Dungeon Finder queuing at home (or waiting for the Raid to be formed, etc...).
TL;DR: Giving us more social options & WORLD interaction options at our homes we spend so much on (whether it be gold or crowns) --- not to mention time! This will definitely make them more useful. I like visiting mine, but will get bored after a bit even though some of them look amazing imo. I put a transmute station & outfit/dye station there and that is probably my most time spent (which isn't a ton, but more than just sitting around).
