Things like the Fishing training book from Booty Bay and the First Aid book from Stromgarde (A) and Brackenwall (H) will fetch a very good price, but even the less rare items like Undermine Clam Chowder recipe (from Steamwheedle Port, Tanaris) can sell well. The Limited Supply routes in capital cities in Legion is still the same route and vendors as back in vanilla. Become a Patreon to The Gold Queen and see the limited supply routes for IF, SW, Darn, Org, UC, and TB, as well as the Booty Bay special, in videos as part of the gold guide I’m still crafting.
You will see a resurgence of power leveling services, item trade services, and gold farming. Classic will have a fresh economy meaning for your average gold farmer time spent in classic is way more efficient. It will probably be worse than it was back in the day. Just look at the blizzard group finder on retail, littered with advertisements for m+ boosting websites. Disgusting. There will be so many gold farmers blizz probably won't be able to keep up. And this is what I truly fear because if the gold farmers start to win activision will step in and introduce wow token. And classic will die.
Greetings! Development of World of Warcraft Classic is underway, and we’re very excited to share some of the challenges and solutions we’re working on. As we mentioned last BlizzCon, the process of restoring the classic game is not straightforward, and it’s important to us to take the time and effort to get it right—this includes poring over numerous game versions, data, and code; meticulously scrutinizing all the changes we’ve made over the years. Rest assured: The WoW Classic team is hard at work making it a reality, and we’re at a point in development where we’re ready to share some of the things we’ve been working on.
