Leatherworking has three specializations: Elemental, Tribal and Dragonscale. I’d pick up Tribal one. It allows to craft Devilsaur set items. Hunters, Rogues, Warriors, Feral Druids, even Enhancement Shamans and Retribution Paladins are among your potential clients. On any realm there is Un’Goro Mafia on Horde and Alliance, they control whole Un’Goro Crater zone and farm Devilsaurs 24/7. They are making thousands of gold. With Dragonscale Spec you are able to craft Black Dragon Mail set. Good demand as well among DPS classes Warriors, Hunters, Shamans, Paladins, for those who wants Bis Pre-Raid items fast and easy. 

World of Warcraft: Classic might be just around the corner, so it’s about time to start preparing. We’ve already published a class selection guide, and today we’re focusing on the most important resource of the game, of course, it is gold. Many players who played World of Warcraft back in the day might remember the times when you needed to count every spent penny and the times when gold farmers roamed the Azeroth on their super expensive epic mounts. In vanilla WoW, gold was everything. And we’re here to help you save as much of it as possible. So, without further due, let’s dive in our World of Warcraft: Classic gold making guide.
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.

As you level, you will buy new ranks of spells. If you splurge out on an item upgrade, you will not have enough gold readily available to upgrade to the latest ranks of spells: placing you behind. Moreover, you can buy gear upgrades from the Auction House (AH) or vendors. Furthermore, you may have large investments that need to be paid for professors. You will need to purchase reagents and items such as leather, bolts of cloth, alchemy supplies – unless you have a charitable friend or another high-level alt.
Earning gold in World of Warcraft: Classic is all about optimizing your spendings. Back in the day, your character’s skills were acquired from a trainer, using money. Don’t just buy everything he or she offers! Read the skill descriptions and be mindful about them. Quite a few characters can live through the levelling process without learning some of their utility or damage spells. These won’t go anywhere and you’ll be able to learn them later on.

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.
Classic WoW is the highly anticipated, upcoming (re) release of the original, first World of Warcraft version, known as Classic and by it's other popular ice-cream like name: Vanilla WoW. Dubbed Retail Classic, or Official Classic by the playerbase - it was finally announced by Blizzard in November 2017, after a lot of pressure from the Private Server World of Warcraft community, since the latter's shutdown of the most popular Private Server called Nostalrius which featured the first WoW version in two separate PvP and PvE servers.
