First of all. Love the announcement and im very excited.
But Blizz needs to seriously reconsider this concept as a foundation of housing.
Simply put, being around other players =/= being social. Or even facilitating social interaction. One needs to simply walk into a capital city in the modern game to see over a hundred players all crammed into one spot doing absolutely 0 social interaction whatsoever.
For a guild? Sure, Neighborhoods will be awesome and im excited for our guild Neighborhood.
But i imagine most people would enjoy the option to simply have an instance based house in an area of the world they like and have a connection to already. Versus a new housing zone that no one has seen or cares about. This focus on being social and such is a farce when your game has already been about spamming instances for years.
You dont create social interaction by simply shoving us all in the same space. You do it by giving us interesting activities that require other people to do.
