So far it seems like the guides direct you to the easiest/best way to get stuff done. The waypoints they use are better than some other places because it tells you how to get to a certain place rather than saying "Go to X place" it says "Go out of the building and down the path" then once you do those things it says "Go kill X mob Y mob and Z mob until you have A items". It has given some pointers too for an area it was like "If you kill a lava thing it gives you a buff so you can walk on the lava" so it tells you to kill some lava things (JC quest in WoD)
The next biggest problem (after time) is deciding the format it should take. It seems to me, these quests will mostly be done while running around doing world quests. Since we can't predict what order someone will have world quests show up in, it is impossible to decide what order to put the quests in. Should it be one guide for all of Horde Kul Tiras and one for Alliance Zandalar, or one for each zone?
The part you need to understand too, is that the Zygor addon doesn't use an App like TSM to update many times per day your auction value. When i bought the gold guide i remember that i didn't understand much either, the results were random and from items i can't make much gold with. It just scans the auction house based on their most recent value update which can be days and days ago.
I only subscribed about 2 days ago after coming back to WoW after 6 years. The game has changed so much since I left right around the Cata release. I decided to start fresh on a new server. I still had all my old links and logins to places like Curse, WowInterface, etc. Loaded up all the addons I had favorited years ago (of the maybe 1/3rd that were still maintained). Got to level 20 in a few hours of playing. Had to look a bunch of stuff up.
