What if Blizzard did not launch TBC however, instead they released an expansion that was built upon the foundations created in vanilla? There are foundations that include neutral battlegrounds, neutral pvp areas and even a chatroom that is cheap WOW Classic TBC Gold referred to as "LocalDefense" (I experienced difficulty getting into it since I didn't know the exact spelling) factions, factions, and many more.
