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.
Allied races aren’t much better. You can only earn them by grinding out reputation. It doesn’t take that long but casual players will need to invest a couple weeks primarily to it, and focusing on that grind will take you away from others, like earning gear. Each race has its own grind, but the things you do to work through it remain the same, adding to your boredom.
EXCEPTION: If you are leveling trade skills while advancing, review the materials requirements of every recipe, pattern, plan, or formula that are planning on purchasing from a trainer. For example, some of the shirt patterns for tailors use very few materials and thus yield a more efficient manner of leveling the trade skill. Check profession leveling guides here on the wiki, ask a guild-mate or friend, or check out information on other web sites to help in this area. A little pre-planning and fore-thought can save you huge investment costs in the long run.
Anyway, however you choose to get to the addon's menu, choose guide list and then pick the zone you want to quest in. There are some zones that will autoselect based on quests in your log, but not all guides or all quests are set up that way. (If you don't want to switch to a guide that auto-pops up choose "not now" or "never") As you can see in the screenshot, there are various categories of guides. Most max level content (such as Argus) is found in Achievements rather than leveling.
Thanks so much for the replies. I think I am somewhat of a collector/roster builder. I go around doing the dailies but I also like buying pets just for their looks. I watched hazelnutty on youtube last night. I think I will focus on doing the expeditions when I have time to get all the pets that come from that. Then I will go back and do old raids like Eekwibble suggested.
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?
