The first problem with this is for LAN parties, I sometimes have 10+ people at one house all playing Warcraft3. The only reason that it works is that we play through LAN rather than battle net. If we tried to connect everyone through battlenet the lag would be so bad that no one could play at all. So I":ve signed a petition and I hope you guys will too. And tell you friends to sign up as well. Blizzard need to hear our cries of outrage!
