Even if the idea is a noble project itself for people who wants it (Personnaly, nah, even now at 27y old with a job, i don't have that much time for this time consuming version), i think will be detroyed by the community itself.
For what i read on multiples forum, they are indeed the true Vanilla community. One part with candid people who really wants to see how it goes, and another one with elitists piece of shit like Alexensual or Kungen, spreading lies to influence the candid part.
The best example is about transmog, they don't want it on the vanilla server (Which is okay, there was no transmog back then, so, pure experience) but the reason is not the authenticity of the server, no no. The main reason is i quote "So i can see which player is a trash or not".
Nice example of the friendship of the Vanilla realms.
But props to them, this was exactly my experience.
Have you tried playing a young casual sp pvp back then?
People spitted on you all the time when it comes for PvE.
I can see where you're kind of getting at some point, but i think the fact of the matter is that no one who plays/likes wow now is going to enjoy the classic version of the game. Vanilla and the version of wow where a majority of people solo old raids for pets/mounts are not the same game.
I'm hoping there are enough people who will want to commit to raiding, as that is how the game will stay alive. Raiding vanilla is WAY less time consuming than current retail, and I say this as someone who is currently raiding on elysium, which has hyperinflated prices on everything due to the massive amount of chinese gold farmers/spawned-in gold from the gm's.
Currently retail raiding requires a pretty substantial time commitment. You're supposed to constantly run M+ and shit to get better gearscore. You gear much more slowly in vanilla which is a good thing. The real hurdle comes with the fact that modern gamers cba putting in ~150h (for casuals) to reach max level. Spending 2 hours getting a group and clearing a duneon only to get nothing out of it will turn people off. Again, hoping there's enough people around to keep a healthy population. I'm lucky since my current guild will migrate over, but it'll be a much different experience for people just relearning the game.
