I am posting a list of thing I personally would like to see in the future of ESO that I hope others will expand on.
I would love to see in existing zones new content with Roaming bosses, Attacks on cities and villages with new monsters, Gods, Villains, and PVE alliances waging war! Even returning Gods to create chaos.
A new Tinkerer class that embraces Dwarven tech for skills with Freeze and fire and lighting rays, teleports, shrink ray de-buffs, anti-magic shields and guns, speed devices and an Ice spray slipping de-buff. They can embrace style looks of Dwarven and steam punk. All this is currently in the game but can be expanded on for a very fun class.
Storage in the Armory! This is a must! I would buy so many more Armory slots if I had the ability to store the gear in the Armory. The Storage needs to store not only the build but the gear and look, mounts, and pets to preserve the theme of the build. I would love to go off on non meta builds for this game but I am limited buy storge space. I would pay extra in the Crown store for this!
Lets us Buy Way Shrines for our Houses to be able to port to other way shrines from our houses. I know we get a free port to our houses but this would allow leaving our house to specific places possible which would be wonderful!
If someone has a set of attunable crafting stations allow all other crafting stations they own in their houses to be able to function like attunable stations. I hate the fact that I have really nice crafting stations that I have earned in game but do not have the functionality of my attunable stations.
Put a lot more comedy like Narcist Dren in the game! I love the comedy this NPC character has given to the game and this game needs more fun comedy quest to add to the adventure of Tamriel.
More themed base harvesting and mining. There isn't enough the game needs more. An animation for catching the fur animals besides looting a box is a must. Like taking a dead animal from a trap to name 1.
More sexy female dresses and Male armor! There isn't enough outfits that reveal our body markings! I mean you make the cool markings lets us show them off!
Make body markings actually show in full glory on vampires! I understand they are Vamps but why do the tattoo's look faded? They should be in their full brilliant effect even on Vampire's.
Make some Staves Spear like and make some rapier swords for outfit styles! And add Crossbow's to the bow styles.
Put in a barber to allow us to color our hair and style it.
Make eye and face makeup separate from face markings! I hate the face that most makeup can not be used with face markings. This was an oversight that needs fixed.
Put a hovering broom and carpet in the mounts for purchase for themed styles. even a horse and sleigh for X-mas. And if you make a Tinkerer class a hoverboard or jet-pack would be nice!

Allow us to tame wild animals and creature as pets.
Now it's my hope all of these things make it to development but would be happy if any at all do so.
I hope others out there clime on board with other Ideas and wishes to support this thread of dreams! So please post what all of you would wish for and even maybe say a here here for these ideas.
Just don't come to this thread and shoot anything down or insult anyone or their ideas. Please keep this post fresh with all wishes for the game.
