I think that the token is a nice solution for the problem. Back in the days, blizzard tryed to ban gold sellers, but it was a lost cause. Instead, the token seems to have resolved the problem, letting workers that want to raid with consumables and stuffs to have the golds to do it. Personally, I don't find the gold buying really fair, but I understand that for many people is a necessity and I prefer to leave the economy and the farming spots to the player instead to the gold sellers.

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.
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 Battle.net 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.
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.
WoW: Classic is scheduled for August 27 (technically August 26 if you're in the Americas). The soonest that you can play it is starting in May, during Blizzard's scheduled stress tests. To opt-in you must have an active subscription on your Battle.net account. If you do, go to Account Management and select the Wow Classic beta. Keep in mind, there will be level caps during the test. The schedule is as follows:
While this might be a change for the better,leveling in Classic will most certainly be different than leveling in Vanilla. In addition to sharding making the beginner zones much more friendly to the hordes and hordes of players storming the gates when Classic comes out, theVanilla leveling process has been studied thoroughly since the game came out 14years ago. Since then, not only have players leveled multiple alts and characters through the beginning zones in Vanilla, but they have done so on a multitude of private servers intended to have the most ‘Blizzlike’ experience. So while leveling a character from 1 to 60 will still be a long, arduous process, it will no longer be marred by mistakes made by players going from zone to zone, continent to continent, searching desperately for a place to level. The zones and routes have been thoroughly mapped out by the Vanilla WoW community at large, and with the internet being much more robust in 2019, that information is just a google search away. Is that a bad thing? I would venture to say that it isn’t, as knowing where to go and what to do doesn’t make it any less challenging and time consuming. It does take away from that exploration aspect,however. You might not have those moments of wandering into Feralas for the first time, or running from Storm wind to Strangle thorn just for the hell of it,or getting lost trying to get to Iron forge from Darnassus on a fresh Night elf.No, those moments, just like many fond memories of Vanilla, are lost in time.

A demo of the game was available at BlizzCon 2018, and was downloadable on home computers for anyone who purchased a BlizzCon ticket or virtual ticket. The servers became available when Opening Ceremony started at BlizzCon 2018 and was set to end on November 8, but was extended until November 12.[4] Players started at level 15, and the only available zones were Westfall and the Barrens.[5] It was based on patch 1.13.0, essentially patch 1.12.0 ported to a modern infrastructure. The first day of the demo, there was a playtime limit of a cumulative 60 minutes with a cooldown of 90 minutes, applied through the BlizzCon Exhaustion debuff.[6] The debuff was removed on the second day of BlizzCon 2018.[7]
