The NPC scan and NPC alert method is an awesome way to build a stock of rare BOE items simply because you don't really have to try. By installing NPC scan and NPC alerts, you can literally just fly over anywhere and be alerted when you pass a rare spawn. As we all know, rare spawn loot tends to have higher item vales, as not everyone is able to consistently farm them. Some NPC's, especially those in outlands have those higher item values when compared to the rest of the world. As a goldmaking method I just everyone should be doing this. It only requires you download two addons and you can get access to important NPC,s that you would otherwise never knew existed. The opportunities are endless, I would generally never play without these cool addons. Realy cool.
For your tank... I'm assuming you meant which race should you be, not which class, since you seem to want to be a warrior! Well, if you were Horde side I'd recommend Tauren for the health buff. But honestly, I *never* pick a race based on the racial features - only based on the flavor. If you are going Alliance side, I am quite partial to dwarf warriors myself but pick whatever seems most fun to you!
By constantly doing quests, you will experience a very different game than if you just level through pure grinding. You'll be out there making a contribution towards the Alliance or the Horde. Doing these quests takes you through the heart of the game's story AND provides the fastest rate of experience. Have fun in World of Warcraft and enjoy developing your hero - your adventures will gain you great reputation amongst the land.
A lot of people ask about good routes to farm when doing these professions, but there really are no special routes to run. If a route is posted online then that area will quickly be overpopulated with people gathering. The best way to go about it is to get the Gathermate addon and spend a few hours gathering all over the zone. You will then get aquainted with the entire zone and where the different herbs or ore spawn, and you will get severel of your own routes you can take depending on if there are other players competing with you for the nodes.
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?
