Ship looks like to be Na players using JP server before it was the ship used to be English speaking on JP servers. With PC realease it was sure that it will be congested cause of newcomers in PSO2 who ignored that fact.
Right now it's an issue even if ship 1 and 3 are normaly populated. Need at last to join the server to transfert characters. Maybe adding this service out of the game on a the website could be a great idea. (i know we have to paid for it in AC) just like blizard have done it.
