1. Storage space that does not reset. Storage space has always been a problem in the game. Even with the bank and the crafting bag, sometimes it's hard to have enough space for everything players want to keep, such as crafted sets,monster helms, etc. Having another place to put them would be nice. Perhaps a shared container that can be accessed form any house you own similar to the way bank storage works?
2. Fast travel directly to houses you own. This could work very easily since it's already set up for the Harborage sites and Group Dungeons.
3. Full sets of crafting tables in at least some of the houses. Having a single place to go to make potions, glyphs and work with blacksmithing, clothing and woodworking would be very nice, as well as a fire for cooking.
