Greetings Soul,
Thank you for contacting Blizzard Technical Support. My name is Mike and I will be assisting you with your issue today.
While I understand your desire for a more personal experience with the game, I regret to inform you hosting or connecting to a server for private use is not authorized by Blizzard Entertainment and is against the End User License Agreement (EULA). Because creating a quality gaming environment requires around-the-clock supervision by our specialized database and development teams this also requires us to have immediate access to our data centers. Moreover, this allows us to implement and analyze patches, upgrades and any other necessary back end maintenance as the need rises.
For further information I recommend you visit our EULA information site
