I agree, something like the permanent backpack spaces. It would be nice to have permanent house slots added. Maybe up to 15 then up to 20 would be nice. The EXP/TP bonus isnt a big deal since it caps anyways. Or at least allow me to lay out all my furniture and have it stay there (just lose bonus) when my energy runs out
Another topic about houses I thought would be fun is to allow players to duel inside a house. Ive always wanted to host a duel competition with brackets and everything. It would be fun and I think have people be more active inside their house. All houses are used for now is storage and housekeepers but there is a lot of potential for more use.
Adding to the topic: What would you like to add or change to the housing system to make it more fun (Keep it clean... lol
House pets... You can have some cat, dog, or even dragon just wondering around the house. They are not really good for anything but maybe they fall over or have some type of animation...
