Good question. Me personally, when I use a new strat from somebody else, I always read thru the strat, and in the case I really need to level some pet, I then (likely) exclude strats that are mentioning things like “RNG”, “risk”, etc. But: I’m always happy (when using a new strat) when I see some detailed infos, so that I can estimate what is going to happen. But YMMV.
However, that’s not the full extent of Blizzard’s announcement. The developer behind World of Warcraft Classic has also announced that it will release a closed beta test for chosen (note this word) players to participate in. The closed beta is meant to test Blizzard’s servers, which I’m guessing will be pretty full once the game actually releases. Blizzard hopes that this beta can prepare them for a smooth launch, since this is pretty big for World of Warcraft players.

I have tried it a few times. It's good if you're new to the game. Otherwise not so much. I found I leveled slower by using it, as it's suggesting to take the longest possible route usually. Basically following roads everytime, when you could take an easy shortcut. Especially if the shortcut involves a bit of fall damage, it's out of question. The "go here" spots don't also update if you take a shortcut, and then the waypoint arrow points to wrong direction. But perhaps it has been updated since then.

To fill our pool of beta and stress test participants, we’ll be choosing dedicated players who meet select criteria from both the WoW Classic beta opt-in and the standard Warcraft beta opt-in. Participants will also need to have an active subscription or active game time on their Account. While opting-in to the beta is the primary way to make sure you’re in the running to join the test it doesn’t guarantee an invitation to the closed beta test. We may also consider additional factors such as how long a player has been subscribed to the game so that we have the right mix of players to ensure great feedback toward making WoW Classic the very best experience for the community.

If you just want the short version of this review, Zygor Guides are the best WoW leveling guides. Period. They’ve been around since 2007, and are always kept up to date and improved, and they have tons of features that set them apart from the competition, not to mention a streamlined leveling path and slick user interface. It’s no wonder that they’re the #1 best-selling WoW guides, because they’re simply the highest quality. Updates are typically released in advance of major patches and expansions.

Most people come here not to read walls of text, they look for the better-rated strategies that match their pet collections, copy&paste stuff they need to import into their addons and only come back if something goes horribly wrong and then mostly to find help in other peoples' comments who also struggled or to find a different team/strategy: I don't think many people wanna read about stuff that already happened to them, they mostly want to see solutions and it's the best way to have them in a well-optimized strategy&team already.
