Even though the guide was developed with a hunter, the guide can be followed by any class. Except you have to do your class's quests which aren't a whole lot. I do have full intention to make my guide friendly with all classes in the future by listing all of their steps as well. There will be a toggle that allows you to show which class's steps you want to see in the guide. But this is coming later.
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. You can find a list of all Essences available in Rise of Azshara here.
It is also worth noting that World of Warcraft Classic isn't exactly an archive from 2006. It has been rebuilt from patch 1.12, using modern data architecture and reaps the benefits of the modern engine. This means a lot of non-controversial quality-of-life features will still be present and it is possible to run WoW Classic servers on modern server architecture. As you can imagine, much has changed in the last 13 years in the tech space. That's before smartphones were even a thing. The modern engine no longer allows certain behaviours that could be used to get out of bounds, also adds widescreen monitor support and accessibility options! However, it does have the disadvantage of not being able to run on 32-bit systems which isn't that kind to older systems considering the game is from 2006.
Some players choose to take a slightly alternative approach to their gold farming. This approach can take an extensive amount of time and dedication. Many people choose to train a ton of alts, solely for the purpose of making money and multi-tasking. In World of Warcraft Classic, professions are usually paired together. For example, if you’re training alchemy, you will need herbs to create consumables (e.g. flasks) that are used for raiding. An intelligent and observant player could seize this knowledge by creating one alchemy alt and one herbalism alt, swapping items as needed between each other. This fully mitigates the fees by the Auction House, which means your profit is maximised. Another complimentary combination you can use is skinning and tailoring, or cooking and fishing.
