Its pretty obvious that many players are looking for a classic experience rather than a 1:1 vanilla recreation if you actually look at the poll. People mostly voted in a way that had the expansion roll out over time and things that damage the classic feel (flying, lfd, lfr) were totally shot down where as a lot of things that just eliminate awkward situations like gbanks have a lot more support. New content and graphics aren't looked down upon either. Many people are just interested in a good game rather than just a purely vanilla experience. Really its a lot like the old school runescape ordeal. You had the purist vs the people who wanted new and exciting content but felt the current game had really just abandoned the principals of what they originally wanted in the game.
As for gold get ready for people to trade current WoW gold for vanilla gold like "WTT BFA gold for classic gold 150 to 1 PST"
