Always post a buyout price on your auctions. Don't think that "They'll just bid it up anyway." Many players will not bid on an auction with no buyout price unless the item's bid price is heavily discounted to begin with. This can lead to bidding wars, but in many cases the item will sell for a fraction of what you could have gotten if you had posted a buyout price in the first place. You will have more sales at a higher price and get your money more quickly if you post a proper buyout price.
Materials ('mats') - items that get used in professions. This is driven more by use than by source; for example, copper is very easy to mine, but it is widely in demand, and you can often find bargains in copper, bargains you can profit from. Contrarily, some very scarce mats may have low demand, may only be used in one mediocre recipe, and may not sell.
After completing your island expedition and second foothold, head back out to your third and final zone to quest in. Note that any legendaries you were using to level have become inactive and are merely stat sticks now. Feel free to replace them with quest gear as you obtain it. Before heading out, feel free to send your three champions out on new missions!
BUT NOW, all the mobs except for the odd rare or boss in a zone are always the same level as you. Every combat is exactly the same. Aggro a bad guy, he runs at you, you go through your standard spell rotation; hit 3, then 1, then 3, then 7, then 3, then 4, then 3, then 3. Then you loot the corpse. It doesnt matter what you are fighting, every combat becomes EXACTLY the same. Boring. Pointless. Meaningless. And then when you complete a level and ding? Every one of your 30,000 enemies dings at the same time and combat stays exactly the same! You gain NOTHING from leveling. It goes from exhilarating to depressing. Why even have different mobs if they will be exactly the same? The could all just be a white blob. Heck, why even have the monitor on, just blank the screen and type 3-1-3-7-3-4-3-3. You could run it on a 70's programmable calculator. Start program, type "31373433" and look at the display for what random percentage of health you have left. Repeat. Again. Again. Again.
Battle for Azeroth has struggled to find a similar role for the player character. The Alliance has largely served as a foil for the Horde. The Horde, on the other hand, are dealing with a deep division. Horde players who do not agree with Sylvanas were given the option to choose a route of defying her ... but this comes after they were made complicit in genocide. It’s not the burning of Darnassus that motivated them, but the follow-up decisions by Sylvanas.
Recipes - provide in-game capability to create more kinds of items, and so are always in demand, BUT be careful; if the ingredients are obscure, and the benefits marginal, or the recipe is too common, this is not a good option. Some otherwise very good recipes drop far to often to hold value - Copper Chain Vest comes to mind. This produces an excellent entry-level item, but the recipe is available for low silver at the auction house.
I'm just now coming back to WOW and TSM after a long time and boy has this incredible addon changed! Right now I'm leveling all expansion version of inscriptions so I'm able to craft all the illusions. I created an All Herb group from this import ( https://www.tradeskillmaster.com/group-maker/ogth3m9d ) but when I search this group in the shopping tab you see it is searching all items (Scanning x/120 in the status). However, only BFA herbs are shown. I verified that this group is using the default, stock shopping operation and validated that operation was indeed stock. What am I doing wrong?
