The waypoint directional system helps you to easily spot and reach a quest NPC or target. The step-by-step guidelines give you an idea of the materials you will at later stages. This minimises the time wasted while backtracking. Your quest progress and level will be updated automatically by the guide. This feature makes it easy to use any character. If you want to take a break or switch to battlegrounds or dungeons, you only need to re-tweak the guide to match your need at hand. Zygor Guides also come with flight path usage, turn in and quest accepting.
An alt (low level or no) in a capital city is an effective way to not only cheaply increase your available bank space, but to be a simple savings and auctioneer account. This character can serve as your bank, an auctioneer, bag-space creator and a time saver. Get one. (There may or may not be Item Recovery issues with characters below level 10, in cases where one's account is hacked.)
Sometimes you can make money by crafting items with ingredients supplied by other players who give you a tip to make the item. This is not necessarily a reliable source at low levels, but it can be a good supplemental income source at higher levels, particularly if you have good recipes. And if you can charge for the customer using your materials (as opposed to materials supplied by him/her), you can mark those up.
I'd say level this toon a bit more, maybe up to 30 or so, and see how you like the experience. If you find questing just a means to an end, maybe the guide would be a good buy. Me, I generally like questing and go to an area I'm interested in, even if it's not the most level-appropriate for me or the best way to maximize my time, so those guides aren't of much interest to me for now.
Each of those modes existed long before this latest expansion; raiding is a basic concept in MMOs, and Mythic+ was added in World of Warcraft’s last expansion. The problems with Battle for Azeroth’s endgame come from the systems it adds, which most often artificially gate progress where most of the fun can be found. If raids and Mythic+ are the carrot, we’re about to talk about the stick.
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?
