The problem does not come only protection timers (which is expensive) to protect our ports but especially the impossibility for European clans to attack ports protected by US or Australian clans that will probably be 5 or 6 am (server time). And if a nation has 2 or 3 US or Australian or Chinese clans that can defend all ports at 4 or 5 am then they will have the opportunity to put all the ports of the nation at this time, and there it kills the RVR totally. This has already been done in the past and it was just unbearable!
