I don't understand this new type of post coming up and complaining about vanilla, or asking for changes, or wondering "why".
Dudes, some people liked vanilla, a LOT. Some still play it on private realms... those people argued, a LOT, for a official version of classic realms, and they succeeded. There is a demand for it.
If you like it, play it. If you don't like it, don't play it. If you are unsure, try it when it releases. Holy hell.
I loved vanilla. Played a -lot- over the past years on private realms like Nostalrius or Kronos, and i sincerely CANNOT wait for an official version. I'll most likely play that over any active expansion for a long time. I don't even mind keeping an active sub for it. If you don't understand why, who cares. Some people really, really like vanilla.
