Character Setup
The good news is that you can use any character in your gold making journey. However, many people prefer to use druids as their primary farming character because a druid with a speed set will be the fastest character in your arsenal and allow you to farm items quickly.
If you are doing transmog or non-current content many dungeon farms contain locked chests, so having the ability to open chests on your farming character is beneficial.
Bank Toon
No matter what character you choose to do farming, it is beneficial to have a "bank" character. This character is usually parked at a faction hub and rarely (if ever) moves away from the hub. The character can be a level 1 character, but should always be equipped with the largest size bags to ensure they can hold a great deal of inventory. This character will be where you post many or all of your auction house items. Any of your other characters that are farming can send all of their spoils to this toon and this toon can focus on managing the auction house. It creates a nice separation of farming duties and auction house management.
Character Classes
Druid
A Druid is a great choice for your primary gold farming character. Feral is popular when you are running dungeons that require speed, while Balance is popular when doing 5-man content where the druid doesn't need to move much.
For a druid that is farming Dungeons the spell is very useful for leaving a dungeon and then casting again to return to the entrance to the dungeon.
Rogue
A Rogue can be a good choice for certain farms. Even if your rogue isn't your primary farming toon, it is nice to have a leveled up rogue to whom you can funnel all of the lock boxes you might obtain from other farming toons. There are also lockbox/junk box based farms where you use the ability to steal lock boxes from mobs in hope of getting a rare item.
Character Professions
When you are farming old content then ideally your farming character has one profession that can open chests (Blacksmithing, Jewelcrafting, or Inscription). If you are using a Rogue, then obviously you don't need a profession to do that for you.
Blacksmithing
If you are farming using a blacksmith, then you want to make sure to craft a Skeleton Key that is appropriate for the content you are running.
Engineering
Engineering is a popular choice for your farming characters due to the utility it provides. The is a great example of utility that helps when running farms where there are a lot of mobs to loot.
Inscription
Inscriptionists can create a to use for unlocking chests while running dungeons.
Jewelcrafting
Jewelcrafters can create a tp use for unlocking chests while running dungeons.
Mining
Depending on the content you are running, mining can be useful. For example, if you are running certain Burning Crusade dungeons, then you may encounter , which still sells for a decent amount of gold.
