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)
1 All expansion guides are written in the Battle for Azeroth beta in order to have them ready on launch day. It's important to note that betas can be buggy and unstable and may delay and even halt our progress on the guides. Furthermore, the time between the start of beta and the announced release of Battle for Azeroth is much shorter (by about 2-3 months) than past betas. As a result, our primary focus is to have the Leveling guides updated by the launch, and only if those are complete and time remains will we work on updating the remaining guides. All guides not finished in beta will be updated post launch. You can read more about this here.
If you want to get rid of all of registries left on the program removal and don't want your Windows system is fill with redundant registries that someday may affect the system performance, you should perform a registry scan and clean with a sophisticated registry optimizer, it will help you clean all the useless and corrupted registry files on the system.
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.
