I think this is what Blizzard was most afraid of when people were crying for legacy servers.
To the people who want the same experience, this post isn't aimed at you. It's more aimed at the 10+ threads I've seen for the day begging for changes to classes, "QOL" changes, questing changes, XP changes etc.
I'm not here to say be "grateful" that you're getting Vanilla servers, in fact I'm happy for you guys. During this entire campaign, I've been curious as to how the "good ole days" were since I wasn't exactly old enough to enjoy Vanilla properly. I'm actually excited to try it. That being said, I know I'm not gonna stick to it and spend that much time on it. But I'll gladly try it out.
But why ask for changes now? Was it such a dream for Vanilla servers that you guys didn't expect Blizzard to do it, and now you want a "Fixed Vanilla?"
If this experience really is changed can it even be considered Vanilla? I'm genuinely curious about this, because I feel like the fight before was "Retail vs Classic" and this is going to devolve into "Vanilla w/changes vs. Vanilla without changes"
