> Blizzard didnt lose the battle in terms of customer experience. Those people mostly played in servers like ggarena with low populations, kinda like WoW.

They most certainly did in this case. This was for the private beta of WC3, not the fully released game. Most people migrated to official Battle.net when WC3 was released, I know I did. They really wanted to keep their private beta private and polish it without the entire world looking in on it.
