Hello,
I dont know why you don't have any answer yet. I totally agree with you. I explain : For now, there is at least 2 server with 2 different playing time (US and EU). Assuming that a human body need between 6 and 9 hours of sleep everyday, the capture timer shoudn't be possible between at least 2 or 3 am and 8 or 9 am GMT in the EU server. And a similar timing should be apply on US server. Maybe a Dev could see what's happening on server PvP 1 EU :
The US nation (mainly play by US people) are taking ports with NO timer (cause we can't for the moment put a timer on a port which was to our nation at the beginning) and they are putting 3am or 4am to 6 am capture timer which correspond to their "awake time" but which is "sleep time" for the others. So the Spain nation can't "defend" their territories, the France nation can't defend and in Pirates nation there is some US players so they try to defend (hardly).
On the rest of the map : wars between Dannish and British are "ok" cause their timers are not during sleep time. It's the same for France against Dutch and for Spain against British. The result is , as say Landsmen, the "timer wars". In my point of view, it's a dead-end for the ports war in PvP 1 EU : it will force players from Europe to get up during nights to take ports back and force US players to do the same (USA nation don't have this problem for now cause majority of ports were already owned by an other nation with the impossibility of putting a capture timer, but they will have this problem in the futur !)
More than "crew moddeling" or "buildings" , developers should focus on that point and come with a solution fast, cause it is really killing the gameplay and the Ports Battles !
