Simply look at the map of ESO and you can see how much room for improvement they have. If they could add a new zone to each faction every six months with quests the game will be interesting for a very long time. Plus they have two other mega continents they can venture into as well as the one sunken continent which is now a series of islands. Could you imagine the underwater adventures you could have there? That is if we could go underwater which I was slightly upset about. Some of the best dungeons were those underwater or partially underwater plus that would open up some more reasons for potions! I would like them to make harmful potions actual poison vials that could coat weapons or put pickpocket in for the rouge like characters so we could potentially sneak up to an enemy and pickpocket a poison potion into a enemies pocket to poison them etc.. There are a great many possibilities that this game could see happen but we as players may need to see an increase in skill points to spend when more content gets added. If done right this game could prove to be very fun for a very very long time.
