Now that you know to loot everything (see tip #1), you’ll have a lot of items in your bags. Any item that is white quality or greater may sell on the Auction House. How do you know what will sell well on the auction house? Trade goods and green quality (or better) items will almost always sell on the Auction House. See our Auction House guide (coming soon!) for more information.
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!
Other decisions were slightly less clear cut. At one point in WoW’s history, there was an 8 debuff limit on any one target. This was later raised to 16, and today there is no debuff limit. Thes change radically changed the balance of classes and strategies players could employ when using these debuffs to overcome content. To preserve that balance—and to avoid the slippery slope of retuning patch 1.12 data to compensate for such modern-era changes—we’re looking at setting a debuff limit of 16 for WoW Classic.
WoW: Classic is scheduled for August 27 (technically August 26 if you're in the Americas). The soonest that you can play it is starting in May, during Blizzard's scheduled stress tests. To opt-in you must have an active subscription on your Battle.net account. If you do, go to Account Management and select the Wow Classic beta. Keep in mind, there will be level caps during the test. The schedule is as follows:
Finally, a clip of WoD: https://www.youtube.com/watch?v=YtKDmlNLVtE&t=5m26s This one I have petattack macroed to a button on the right-side action bar, 2nd from the top left side (icon looks like a bone bow). You can see my bird pet take off INSTANTLY when pressed. I realize this one doesn't prove much regarding Classic, but this is proof that it WAS functioning this fast until Legion. You can see the delay on Live yourself by logging into BFA.
Leatherworking has three specializations: Elemental, Tribal and Dragonscale. I’d pick up Tribal one. It allows to craft Devilsaur set items. Hunters, Rogues, Warriors, Feral Druids, even Enhancement Shamans and Retribution Paladins are among your potential clients. On any realm there is Un’Goro Mafia on Horde and Alliance, they control whole Un’Goro Crater zone and farm Devilsaurs 24/7. They are making thousands of gold. With Dragonscale Spec you are able to craft Black Dragon Mail set. Good demand as well among DPS classes Warriors, Hunters, Shamans, Paladins, for those who wants Bis Pre-Raid items fast and easy.
