We have no idea what implications this might have and whether or not it even indicates anything, since Patch 8.2 is still in testing and a Tuesday launch is more than unlikely due to Essence tuning and Azshara's Eternal Palace, which is supposedly coming shortly after launch. Blizzard said they wouldn't be delaying the new raid like they did with Battle of Dazar'alor.
What am I supposed to do now? Is there a way to get the curse client working again? I've googled it but haven't found any useful results. Do I have to uninstall & re-install it from scratch? Has the Curse client been taken permanently offline, meaning that it's no longer viable software? Do I have to install a Twitch client and manage my WoW addons from there? If so, do I have to re-install all my addons from scratch, or will they somehow carry over from Curse to Twitch?
Drustvar is far and away the hardest Alliance zone, which is exactly why you want to do it first. If you have legendary items, they’ll still be usable, and if you don’t, this zone will still be easier early on than it will be later. Drustvar is also extremely fast and will let you jump out ahead of your competition in other zones, which means fewer players around to take your quest objectives.
