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.
Where to get materials and reagents you may ask? Buy for cheap off farmers in bulk or track Auction House lots. Get in touch with most big sellers. Communication is important here, send a whisper or write them a letter. It would be good for both of you to establish business relationships. Constant suppliers and buyers is convenient for both parties to save the time and effort.
There is an Action Bar at bottom of the User interface. Each class starts with some skills. Every few levels, you will unlock new skills specific to your character class, these can be learned from your Class trainer. You will be introduced to one of these NPCs during one of the first few quests you complete in your starting zone, but they can also be found in many towns and each of your Faction's cities.
Escort quests can take awhile to do. I have thoroughly tested all the escort quests in the game for time/xp. Most are worth doing, but as long as you are able to actually do them without failing. Most require you to pay special attention to the escortee as most are fragile and will die easily, so do your best to keep mobs off of the escortee during escort quests. The longest one in the game is the Tanaris chicken escort. The chicken escorts are only worth doing if you were able to do all 3 of them, as if you do, you will be able to turn in an additional easy quick XP turn in quest at BB, which makes them worth it.
World of Warcraft (also known as WoW) players have highly requested the classic version of their favourite game. As with any game, changes and major updates are added over the years. Since August 2006, many changes to the game have not been received well: such as trivialising levelling up. The level cap will drop from 120 to 60, but contrary to how that sounds, it will be a far more grindy journey of fun and progress. The current developers have made levelling up very fast in comparison to the classic days, purely to focus on end-game content and raiding which many people do not enjoy. Prior to these changes, many people enjoyed the games for years whilst not hitting max level, something never seen in the modern edition of World of Warcraft. The levelling process was a journey, having fun with professions and the grind that is no longer found. Of course, there are countless other changes that will be reverted, as you might expect when comparing something from 2006 to 2019.
