Kaivax, a WoW forum community manager, revealed that WoW Classic's class design, battleground mechanics and stats on existing items will be set to their 1.12 state, despite the game releasing content that expands beyond that. This removes "progressive itemization," so if the stats on a specific piece of equipment was changed during the original updates, that won't take effect in this version.
Cold Eye Basilisks (marked RED on the map) - Western shoreline of the middle Stranglethorn Vale is infested with deadly Basilisks. These monsters are a good source of Heavy Leather and Thick Leather (we recommend Skinning for this spot), they also drop a lot of Vendor Trash Items (Curved Basilisk Claw, Intact Basilisk Spine, Large Basilisk Tail, and Squishy Basilisk Eye), Large Fangs (used in Leatherworking, Blacksmithing, and Alchemy Recipes), Wicked Claws (used in Leatherworking and Blacksmithing Recipes), 12 Slot Bags, and most importantly, Cold Eye Basilisks have a small chance to drop the Cold Basilisk Eye (a level 35 BoE Trinket, that can be very valuable, because useful Trinkets are rare in Classic). Recommended Level - 38+.
Thalassian Base Camp (marked BLUE on the map) - Some Blood Elves have set up a camp in the northern parts of the Azshara. Blood Elf Reclaimers and Blood Elf Surveyors that can be encountered in the said camp are rather easy to kill and have very good Loot Table. The most notable items dropped by those Elves include Runecloth, Mageweave Cloth, 16 Slot Backpacks, various Vendor Trash Items (junk weapons, armor, and so on), and Pocket Money. They can also be Pickpocketed, so this spot presents an additional value for Rogues. Blood Elf Reclaimers have access to strong Fireball, Heal, and Renew Spells, so they should be interrupted when possible and prioritized. Recommended Level - 52+ (54+ to be extra safe, and farm Elves at an increased pace).
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.
