the guides work great for leveling almost in autopilot, also the zygor guides work great, the only problem is that this 2 companies moved to a monthtly fee payment model for BFA, not worth the money that you are paying if you ended up paying almost the same as the game monthtly subscription. Recently there is a new free addon for leveling in curse addons webpage that do this without the payment, is not as advanced like the pay ones but works. i will leave the link below. We need to support this kind of free addons.
Dugis Ultimate world of WarCraft Guide installation is not impossible, nor should it deter you from using another guide; remember many are very satisfied with Dugis Guide. However in order to install Dugi’s WoW leveling guide you have to download their installer, you have to download each part of their guide individually (about 16 files).  Once you have all the installation setup files and the installer in the same folder, you execute the installers.  All the installer does is UnZip each file & place it in your Addons folder.  The process is very similar for the Macintosh.
World Quest Tracker permet de suivre les différentes expéditions en cours dans Zandalar et Kul Tiras depuis la carte de la région. Cet addon permet d'avoir une vision d'ensemble des expéditions et vous permet de cibler directement celles qui vous intéressent, sans avoir besoin de passer votre souris sur chacune d'elle pour regarder la récompense. World Quest Tracker permet de gagner un temps précieux dans le farming des expéditions.
Possibly the most complicated Addon I have ever used it is also one of the most powerful. You can build custom Visual and Audio warnings for virtually any situation in the Game. I have used it for Buff Stacks Low HP and Ability Cooldowns many times over the years on various Characters. Blizzard added similar Visual Warnings in Cataclysm.Git Repository: 

Functionality is the heart of these guides, what you are really paying for.  There are a lot of aspects I could look at with regards to functionality such as; questing path; quest progression; addon user interface; bugs; performance and many more.  All that we are concerned with are questing path (speed) & user interface.  All the other aspects aren’t worth comparing as both wow guides are light in terms of system usage, both have very few bugs, and both update your quest progress in real time.
