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.
Arms: Sharpen Blade - When activated, your next Mortal Strike will deal 15% increased damage and reduce healing taken by 50% for 6 sec. Fury: Battle Trance - You go into a trance causing you to regenerate 3% of your health and generate 5 Rage every 3 sec for 18 sec after using Raging Blow twice in a row on a target. Using Raging Blow on a new target will cancel this effect. Protection: Thunderstruck - Thunder Clap roots all targets for 1 sec. Tuning
That's not to say that everyone has an unrealistic vision of what vanilla WoW was like. There were already plenty of people on the WoW Classic forums pointing out that perceived bugs are just recreations of the original game. And as noted before, a flaw to one player is a key component of the original positive experience to another. WoW Classic will surely please plenty of purists in spades. But this goes to show that it won't be for everyone who has fond memories of the game circa 2006.
