I consider myself a purist in that I would prefer classic to be released as close as possible to the original. Where that is on the spectrum of patch content will be up to blizz. I'm also not vane enough to believe that any single state of the game is the "Ideal" location we should be aiming for. There is common ground that we can agree on, and I would welcome more than a few changes as long as they are made in the spirit of keeping classic on the vanilla rails.
With all that said, getting in the WoW Classic beta could be a bit challenging, as it is invite only. In order to have a chance to participate, you must sign in through a Blizzard account and opt into the beta through the account management tab. The team at Blizzard will begin sending out invites on May 15 for the first WoW Classic beta period. If you have yet to sign up, do not worry, because more beta testers will be picked as future beta periods get closer.
I am currently working full time on my Vanilla WoW leveling guides. Soon there will be a 1-60 speed leveling guide for Alliance, along with in-game guide versions available for my members area. As of right now, there is no members area, but if you would like to show support for my efforts into this project, you can simply donate to me via Patreon if you like (you will get some cool rewards in return). Or you can donate directly with PayPal if you like. All donations are highly appreciated and they will only motivate me more to continue making the best vanilla WoW leveling guides on the web.
