You play with my feelings ...

Piracy is not just an excuse. In fact LAN could be used in Warcraft III to bypass the CD-Key and to play on the Garena platform. The Platform offered an own ladder and you don't need a legit key to play there. Thus they lost a lot of money as people never ever bought anything, but played the whole day. (For example most of the player I know from the Ukraine play this way - just talking about experience)

Now Blizzard will most likely allow to play LAN, but only if both have an internet connection and are connected to BNet with a legit key. (You don't play on their server but need to be connected to it)

Just my guess / two cents :>
