I've used WoW-Pro for years and in WoD, Legion and now BfA it's been awesome for just going on auto-pilot and working your way through a zone. It has 3 levels of depth you can set, so you can set it to just do 1) the main story, main points of interest and rare mobs and treasure that aren't far off the beaten path; 2) every quest with a more thorough dive into the side stuff; 3) absolutely everything.
Determine the gear stats and armor type you need for your new character. For example, a paladin requires Strength as their main stat, and heavy armor (the armor type) will scale as the character scales if they are initially unable to wear heavy armor due to being a lower level. Your optimal heirloom gear set will feature the same main stat as your starting gear.
No he's just not paying attention. The wanted quests are built into both the leveling guides and the "Zandalar Forever" achievement guide. They aren't in the rep guide because they are not repeatable and by the time you hit max level they should be done. You'll also notice the rep guide doesn't contain every single possible completable quest that rewards rep. It is designed to focus on repeatable objectives, world quests, large quest lines, and missions.
Never ever pay for leveling guides. Want/need to learn about and use. Dugi is hosting a contest where you can get. Saharun is one of croatia's loveliest but least known spots (picture: alamy). Open my map to see where the nearest quest takes place and go there, through the questtracking you can quickly see what is to be expected of you or even when you look at your tooltip while hovering over mobs. It sounds unrealistic but the video promotion of the guide clearly shows how you can do it. Unfortunately it is a website and you may have to tab out if you aren't sporting a multi-monitor set up.
