Anyway I will go ahead & download the Twitch app like everyone's saying, but I still need to know whether my in-game addon settings will carry over automatically, or whether they'd return to default same as if they'd all been uninstalled in the curse client then reinstalled from scratch. Because if it's the latter then I will have to take screenshots of the settings on all my toons BEFORE I install the addons thru the Twitch client.
Azeroth Auto Pilot est un addon qui a servi à Method à décrocher le world first niveau 120 en moins de 5 heures de jeu. Programmé pour vous faire suivre le chemin optimal pour monter de niveau, il s'agit non pas d'une aide, mais d'un véritable GPS qui vous indique quelles quêtes prendre, où aller et dans quel ordre faire les quêtes. Cet addon est recommandé pour les joueurs qui n'aiment pas prendre le temps de monter en niveau.

Don’t waste your time in vain, and immediately go in search of adventure.
A: We chose to go with the subscription-based model instead of that approach. We've taken the approach that we want players to feel like it's a level playing field once they're in WoW. Outside resources don't play into it -- no gold buying, etc. We take a hard line stance against it. What you get out of microtransactions is kind of the same thing and I think our player base would feel betrayed by it. I think that's something else you have to decide on up-front instead of implementing later. 

- The auto trash sell feature is also incredible, but I always had issues with it selling gear efficiently. Often I have to open my bags 2-3 times if I have a lot of trash, because it can't clear it all in one go. There's also a very noticeable delay with this feature when opening the bags, almost like the bag UI is freezing for a few seconds, then it clears. I've started using a different add on for auto selling trash and it does it all instant, no hiccups, no nothing. Just one swift move.
Dugi guides is a guide to the world of warcraft. The addon also helps you locate quests and quest givers that are in hidden places. Grab everything you need to play like a pro. (all 12 of them) – earning you achievements, gold, reputation, pets and other goodies. Brbinj - surrounded by thick olive groves. There are a lot more features that you can read about on their website, but let’s just say that dugi’s leveling guides rock. Instance leveling is truly a great way to power level your character, and you’ll probably even discover dozens of classic and burning crusade dungeons you’ve never played before.
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.
I just leveled this char in about 2 days played time with a few hours of it being afk in cities.What I did was run every single dungeon one time and do quests while waiting in queue.That way you don't get bored and the experience gain is great.Works particularly good between 60 and 90. WoD is a piece of cake if you just have flying and Legion is questing + doing the per zone dungeon for the 100k xp quest.

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.
