Vanilla "kids" and "young at heart" are much older now. Vanilla was 15 years ago, a time when WoW was growing, to it's peark in TBC / WotLK. People playing have seen the difference, enough to know what they like and what they don't like. They discuss things they love. They discuss things they hate.
WoD is being related to BFA-- bad timing for nostalgia. Nostalgia, does it exist for WoD?
If you love WoD, get a website and a twitter account. Get a following to back you.
