EVE online thrives on truly massive space battles and CCP are doing their best to ensure that such large concentrations of players do not cause undue server lag. Even still I am a bit taken aback by a request in the latest newsletter for players to notify CCP in advance if they are planning a large fleet engagement. The announcement contains dire warnings about abuse of the system but I am still not sure.
To quote Sun Tsu: In conflict, direct confrontation will lead to engagement and surprise will lead to victory.
So if you are planning a surprise ambush on the heartland of Band of Brothers so you really think it would be a good idea to notify CCP in advance?
