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.
I also wanted to note that a lot of users, I found on the Web claimed Dugi’s Guide to be faster. However, all these users had either used Zygor Guides for very little time or had not used it at all. I have to give a point to each Dugi’s Guide and Zygor Guides as they both deliver a great lvling speed. For all you Dugi’s guide users out there who really feel that Dugi’s Guide is faster, I will give Dugi an extra point. If there really were a difference, it wouldn’t be by much.
