CIG made the very smart decision of founding their game on the Crye Engine, an engine with notorious network problems, not meant for more than 14 people in a server. Theaters of War is a good example on how the servers may never be able to handle the game! If Battlefield could have 64 player massive battles, with vehicles and all for many years, then why cant CIG figure it out with Theaters of War? Its because the engine can't handle it.
