EDIT WITH UPDATED BLUE POST INFO. Thank you to Eloraell for posting it in here.
Stress Test Details – June 19
Just a little information packet for everyone to help clear confusion before they make 4000 threads about it.
Tomorrow is an OPEN stress test. Pretty much everyone is able to participate. Downloading started early today. If you don’t have any options to download, your battle.net launcher should do an update, then restart it and in your regions dropdown you should have the option to download World of Warcraft Classic under where it says LIVE. Once it downloads and installs you should be able to open it and see a long server list, all inactive until tomorrow.
There can also be another option in the dropdown that says Beta: World of Warcraft Classic. This does not mean you have beta. It’s the client they were using for both beta and stress test, but they created a new one specifically for stress testing and separated them from the beta client. The Beta client play button will be grayed out if you don’t have Beta. Blizzard keeps this launcher here so that you can more easily uninstall the beta client.
It is advised to keep the World of Warcraft Classic client, the one under live, as this could likely be the client and platform used when the game launches. Keep it pre-downloaded and updated!
– Added: If you do not have a sub it’s unsure on whether you’re going to be able to play or not. The best advice I can give is to monitor the forums tomorrow when the stress test starts. If people start posting about getting into the servers, and you’re unable to, then it would be the subscription requirement.
tldr because apparently this is too long: Update launcher. Restart Launcher. Check Region Drop down. Beta: World of Warcraft Classic might show up. If button is gray. You don’t have beta. Here so you can uninstall beta client. Under LIVE there is World of Warcraft Classic. This is stress test for everyone. Starts tomorrow. Download it. Install it. Doneso. – How’d I do?
