What I miss about Vanilla is:
>slow, deliberate and meaningful progression
When a good weapon drops, I am very happy. This is a rare occurrence, and I won't replace this weapon for maybe several IRL days.
Today, you are rewarded too often, and the rewards lack impact. A good weapon is replaced within 2 hours of play by the next good weapon that drops.
Yes, I advocate being slow and ""grindy"". It feels better.
>community and local celebrities
No cross-realm and anonymous group finder means that people will remember you personally. You will remember the name of that one really good tank, add them to friends, notice them in chat or in the world, group with them again. There is reputation and someone ninjaing loot can mean nobody ever groups with them again.
Basically voluntary honor system, where the community ostracizes garbage humans, and reward decent people. Also the best PvPers are celebrities, well known and liked/hated.
>somewhat functional economy
Everything costs money, you can sell more or less anything you find. A level 5 character can make a buck selling copper he mined outside of Orgrimmar. You need to use the AH to get certain items, you need to befriend people of different professions so they can craft you the gear you want. Crafting that depends on dungeon and raid drops.
>open world
World of Warcraft is about the world of Warcraft, yet 90% of the time right now is spend in capital cities and the few daily dungeons.
People should walk around the world, meet others who will ask them for help, meet enemies to fight in world PvP, randomly stumble on a rare monster, etc. This means no flying, and no teleporting from the auction house to the dungeon. You have to fucking get there. You need to be in the world, and thus be a predator and target for ganking, and be available for other people to recruit for group quests, meet people, etc.
I want THESE things. Visuals, animations, balance, new races or classes, I don't care. They can add them.
