Invest - If you do not plan to rush to level 60 and want to take your time instead, this tip might come in very handy for you. The value of many Items will increase over time because more and more Gold will find its way to the market. To take advantage of this, you can stack up on various crafting materials with the intention of selling them on a later date. This will require a lot of patience and some Grinding if you want to make a good profit but is certainly worth your while if you are an economy-oriented Player.
Legashi Satyrs (marked RED on the map) - Lageshi Satyrs, found in the northern Azshara are a great source of Runecloth, very valuable Felcloth (the main source of income from this spot), various Vendor Trash Items, and some Pocket Money. They can also be Pickpocketed, so Rogues will make additional Gold in this Spot. They have an annoying Mana Burn ability, so using an Interrupt is in order for all mana-based Classes. Satyrs also carry some Demonic Runes, that can be used to restore Mana at the cost of Health (basically, a Life Tap ability in the form of a Consumable. Those can't be sold on the Auction House, sadly, but are very useful nevertheless). Recommended Level - 50+ (52+ to be extra safe as Satyrs can be problematic because they tend to run away on low health and pull additional enemies).
Monstrous Plaguebats (market GREEN on the map) - These are larger cousins of the normal Plaguebats. They occupy northern parts of the Eastern Plaguelands and drop Vendor Trash Items (Evil Bat Eye, Bat Ear, Sleek Bat Pelt, and Large Bat Fang), Wicked Claws (used in Leatherworking and Blacksmithing Recipes), and maybe some 16 Slot Bags. These can also be skinned for Rugged Leather, Thick Leather, Thick Hide, and Rugged Hide, so Skinning Profession is recommended for Farming them. Monstrous Plague bats have access to the Sonic Burst ability, which is a 10-second Silence, so they are not a good choice for Spellcasting Classes. Recommended Level - 56+.
Some players have been surprised by these apparent flaws—even players who have been eagerly awaiting WoW Classic's release based on fond memories of vanilla WoW. In truth, it has been so long since WoW first released, players' memories may not always be accurate. Some details might be fresh, but others might be lost in time, and it's those lost details that could surprise players revisiting the original experience in WoW Classic.
