Another thing I'd do is revamp the overworld. It's a pretty world in many spots but there's not much to do other than questing and FATEs. I wish there were hidden quests and treasures and cave systems etc.

Elder Scrolls Online can be a janky game at times but its overworld is amazing and I really wish more people would take notes on how it handles that. In ESO you will probably spend most of your time out and about doing things in the overworld (world bosses, public dungeons, looking for treasure, collecting crafting materials, finding skyshards to improve your character, archaeology, questing....)
