As of right now, there is no official exact release date, aside from confirmation of summer 2019. It is expected to hit the internet roughly mid-July, or possibly in August. Something as highly anticipated as WoW Classic could launch with weeks of notice and still break records. As of April 21st 2019, World of Warcraft Classic has entered internal employee alpha testing.
So, if you happen to have two good 1h weapons, and are Fury specced, don't be afraid to try out dual wielding. Some people swear by it, and I can see why. Getting miss/parry with 2h weapon is cancer, and having two weapon swings for two different chances at crit, can really help smooth out your damage and make it less random. If you're still skeptical, I'd suggest trying it out once you get Thrash Blade, or if you happen to have a Flurry Axe. With really sick 1h weapons, dual-wielding can definitely feel great.

Extract ConsolePort to Interface/Addons. The addon can be downloaded through the Twitch app too. Make sure the addon is enabled when you log in to the game. Install WoWMapper and connect the controller to your PC via cable or bluetooth. Make sure the controller is recognized by your operating system. Log in to the game and make sure ConsolePort is enabled. Now it's time to choose your controller layout. Grats, you can now start playing the game with a controller. (Optional) Enable Action Camera for extra immersion by typing /console ActionCam full, /console ActionCam basic or /console ActionCam default, depending on whichever you prefer most. You can turn it off by typing /console ActionCam off command.
