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.
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.
Loot everything - Every single item in the game has some value and you should take advantage of this fact. Grey items can be vendored for that little bit of extra pocket money and white stackable items are needed for crafting, which means that people will generally buy them if you post them on AH for low enough price (if you can't be bothered to post Auctions, you can just vendor all of them and be done with it). Some of the looted items will rise in value over time, so you might also want to take your time and store them on Bank Alt.
There are 5 Dreaming whelps and 7 adolescent whelps spawns, They drop the small flame sack which sells for a decent amount at auction house or can be used to make fire protection potions. The sacks have around 10% chance to drop and it's one of the main reasons you want to grind here. On top of this you'll get lots of grey items, green and blues with a higher chance than your average mob. If you are not aware yet, dragonkins have the best loot table in the game while having less HP and armor... making them easier to kill, assuming you're not fighting elites...
