When it comes to levelling the Priest Class from 1-60 fast, XP grinding locations is only half the battle. You will need to make sure your weapon does enough DPS so that you can clear these mobs fast enough, it should also be noted that monster should be around your level to make sure to gain the 100% XP Reward. The Level your character should be before you start that specific location will be indicated to left in a Blue Color for Alliance [Lvl 35-39] and the Orange Color for Horde [Lvl 35-39]. The Mobs you are looking for in that specific area names are Bolded [Mob Name].
So committed, in fact, that modern WoW players are trying the beta and reporting what seem like bugs today but what were actually intended functionality 13 years ago. This became such a common occurrence that Blizzard publicly posted a list of known non-issues called the "WoW Classic 'Not a Bug' List." For example, hitboxes for the Tauren player race are much larger than those of other races. In a modern game, this would be seen as a serious balance issue (see: Apex Legends). But it's what vanilla WoW was like, so it has been faithfully reproduced.
I am currently working full time on my Vanilla WoW leveling guides. Soon there will be a 1-60 speed leveling guide for Alliance, along with in-game guide versions available for my members area. As of right now, there is no members area, but if you would like to show support for my efforts into this project, you can simply donate to me via Patreon if you like (you will get some cool rewards in return). Or you can donate directly with PayPal if you like. All donations are highly appreciated and they will only motivate me more to continue making the best vanilla WoW leveling guides on the web.
Players should keep in mind if you want to gain the full 100% XP reward from killing mobs they will need to close to your current level. With that in mind below we list each location you can grind levels 1-60 with the Mage class. The Level your character should be before you start farming in that specific location will be indicated to left in a Blue Color for Alliance [Lvl 35-39] and the Orange Color for Horde [Lvl 35-39]. The Mobs you are looking for in that specific area names are Bolded [Mob Name].
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.
Kurzen's Compound (marked BLUE on the map) - Colonel Kurzen was once a very talented Stormwind Officer. He was sent with an expedition to the Jungles of Stranglethorn, where he fell victim to Mai'Zoth, a powerful Ogre Mage and his foul magic. Majority of Colonel's troops are still loyal to him and provide Players with some valuable Loot. In this spot, you will encounter Kurzen Jungle Fighters, Kurzen Medicine Men, Kurzen Wranglers, and Kurzen Commandos. These Humanoids drop a lot of Silk Cloth (that can be generally turned into Bandages and Vendored), valuable Wool Cloth (the main source of Gold from this spot, check the AH prices), Fadeleaf (Medicine Men), Liferoot (Medicine Men), 12 Slot Bags (Commandos), Vendor Trash Items, and some Pocket Money. This spot is especially good for Rogues, as the ability to Pickpocket mobs will increase profits by a noticeable margin. Recommended Level - 34+ (36+ to be extra safe, as Humanoid mobs can be problematic because they tend to run away on low health and pull additional enemies).
The Horde 12-20 (Barrens + Stonetalon Mountains) guide has been rewritten and revamped. In addition, there has been numerous tweaks to the speedrun route to make things faster and easier to follow. Also, in case you haven't noticed I am now adding about 40% more info per step and redoing all the images. Unlike with my previous vanilla guides, I am now giving a brief explanation of where to go and what to do with each step along with any other helpful tips.
