There are more passive methods to gain wow classic gold, but these are slower. For example, many people choose to fish in places like Tanaris, or kill Harpies in Feralas and loot items such as mageweaves. These are rather AFK-able, but again, not as rewarding. Some people choose to favour fun over anything, and like in any MMO (massively multiplayer online game), the best way to have fun is playing games with friends or your guild. Dungeon runs with your friends provide social interaction and are definitely helpful over the long-term for your gold stack!
Note: My goal here was to create a comprehensive list of everything you'd need in order to learn to play any class (from Level 1 to Naxxramas)—meaning I am only including class-specific resources here (so no profession guides, general leveling guides, etc). Teeb's Resource list is much broader in scope, and I highly recommend you take advantage of it (as it contains a plethora of non-class specific resources as well). If you're not aware, Teeb is also responsible for the Race & Class Comparison Tool, Dungeon Tier Sets Gallery, and a huge variety of other insanely useful resources.
For another example of lighting, we looked at Elwynn Forest. We had a period in Warcraft’s history where we changed all the lighting equations and as a result, our environment artists had to take a pass over all of the zones to improve the lighting and take advantage of the new equations. To recreate the original experience, we had to rewind those changes. The first thing we did was restore the old lighting data. This brought us much closer to the original lighting—and with a few more changes to the distance formula, fog formulas, and some changes to shadows, we were able to bring things even closer to the original lighting.
You will have to talk with flight masters in most towns or cities you visit in order to gain access to that settlement's flight path. Flight masters who have a stop you have not yet unlocked will have a green  displayed above their head (and on the mini map), much like a NPC with a quest. Unlocking flight paths as you progress through various zones will allow you to pay for a quick ride to a destination you have previously visited. This method of travel is significantly faster than walking or riding a mount. 

The company has provided a list of the most commonly reported gameplay elements that Classic players are reporting as bugs, including warrior health regeneration rates, the lack of quick objectives and POI tracking on the map/minimap, the presence of a dot as the marker for completed quests on the minimap, fast running NPCs, and slow creature respawn rates (full list below).

This is for those who want to own a piece of Vanilla WoW history!  This tier requires your physical mailing address so I can mail you the printed paperback binded mini leveling guide/book.  By default I will sign "Joana" on each book!  If you wish for me to write something else out (such as my real name) you can request that as well.  And finally, thank you for the support and I will continue to make the best leveling guides for WoW!
You can’t go wrong with a mage. In fact, Mage was the most popular class in World of Warcraft: Classic due to their ability to farm with ease. Back in the day, the player majority even leveled mages as alts in order to gather gold quickly. In addition to their monstrous ranged DPS, mages also have tons of useful utility. As a mage, you’ll be able to conjure food and water, place portals to the major cities, and even earn gold from doing so.
Gold in World of Warcraft Classic is an integral part of the game. In this article, we will discuss the importance/role of gold in vanilla WOW and how you can obtain it easily. Gold was vastly more important in classic; it gradually became less relevant/powerful as time went on in the current version of the game. It is very tedious (but not difficult) to gain gold in vanilla, which is why many people choose to purchase gold.
