-Mount Raising (Being able to raise a Mount from a baby and the choices you make will influence the Starting stats and dare I say Color of your mount. This could be simply a quest with choices that results in a Mount or some kind of a daily excursion where you need to Feed it and Train it on a daily basis to influence the starting stats at adulthood, and you will eventually after a week or 2 be able to ride it.)
-Player Housing (Yes, yes. We have been asking for this, because its fun and awesome. I would love to see a Zone specific for Player Housing, where players can walk around and see how other people have designed their place. Have the Owner decide if the doors are open to the public or closed.)
-Achievements with gear(costume) for rewards (something wearable, so you can show off by just wearing it, it can be statless but looks awesome.)
-Quests that take you all over the world (This way Nirn will feel more like a World and not just Zone after Zone.)
-Gear with stats that enhance your mount (Would be popular for Harvesters who just want to ride faster from node to node and Look fabulous. Or it could be in the form of a Trait so it may be viable in PvP. But, I was hoping more for a Style associated with it in order to bring more Unique looks to the game.)
-Vanity Pets with bonuses (Pending we get the ability to hide other peoples pets. If we have more of a reason to have pets out, people will want a way to not see other peoples. My biggest 3 ideas for these are:
A Pack Pet, that holds 10/20/30 Items for you in its own personal Inventory. The Rarity of the pet the more Inventory he holds. (Blue, Purple, Yellow Quality).
An Auto-Loot pet, something that picks up the loot for you from the mobs after you kill them. So, you don't have to go click on everything you kill.
A PvP Buddy, a Pet that starts to make noise (bark if its a dog) if there is an enemy player in close proximity to you, in Cyrodiil.)
-Furniture crafting (to go with the housing. And your house has its own specific Inventory UI. Lets say it starts with 25slots for owning the house and you can drop your mats into it or add in a Desk or Cabinet to increase the Size of your inv. (example: 25 original slots, put in a Desk that costs 1 slot but adds 5 = 29 slots. or 25 original slots, put in two cabinets that cost 1 slot each but add 10 each = 43 slots. Also, perhaps add in Alliance Motifs so you can craft Furniture of the other alliances for your home, Lets say you get them from completing Cadwells Silver and Gold respectively. This will give players an incentive to want to complete them.)
-Player Titles with stats (give us a reason to want to get those Titles from achievements.)
-Barber (Enough said, a lot of us want this and it was Stating to be coming Soon.)
-Immersion quests (like deliver a package from this town to another town in a specific time frame without using wayshrines or teleporting. and its Repeatable.)
-Diving underwater (with fighting in the water. They had it in almost every other ES solo game, so theres no excuse to not have it for ESO eventually)
-Solo Repeatable Instanced Dungeons (Just like the 4-man but designed for 1 person.)
-Instanced Boss Only Fights (A long Boss fight designed for a party [or alliance] that is consisted of Stages, usually taking upwards of 30-45min to complete.)
-Gardening (where you can harvest your own crafting mats after a few days when the plant grows, if you take care of it, perhaps have it combined with your person house in the housing zone.)
-Escort Quests (where you have to protect an NPC on his journey, and if the NPC dies, you loose the quest. This can be a Dynamic event like the Daedra rifts that pop up randomly as your questing.)
-More weapon types (we are still missing a lot of amazing weapon types, enough said. Such as: Hand to hand weapons, Polearms, Whips. I would love to see at least another 6 weapon Trees for more options for everyone.)
-One-vs-one Dueling (We have all been asking, enough said.)
-More Classes (We have 4 basic ones, but we could still use more. Such as: A Bard Class and one of the Trees can be focusing on Buffing your fellow party members. Always a great idea for future Expansions to give veteran players a reason to make a new toon and play the game again from the beginning.)
-More Immersive travel (Such as: a Cart that you can ride from town to town, or even just a Rent a horse that you ride to another town. Both travel types are Automatic but have an option to Jump off when you wish, perhaps in order to get to a specific place that you may not have been able to get to naturally from a Wayshrine.)
-Yearly Global Events (Like Holidays or just Special Events run by the NPCs of ESO, usually bringing a quest to do that rewards you with a Costume for completing it. These quests only last a short amount of time, so you have to be there for it to get your Rare Costume, or have to wait till next year.)
