The current system is a system that makes absolutely no sense for PSO2 and NGS. I don't understand it and I don't know why they thought it was a good idea. I have been voicing my complaints about it since day 1. Being locked to one ship only has negatives, there isn't a single positive, and the negatives are much much worse for those on ships with lower players. I will never be able to play this game with certain players on this forum because they are on a different ship, that just seems nonsensical too me. Why implement a system like that?
Think of all of the possibilities that would come from being able to jump servers any time you feel like it. More players to meet and play with, the world feeling more alive, easier to find players to do certain content, a much better player market.
It just feels like an unnecessary restriction and hurts the game in the long run. I couldn't imagine getting much fun out of playing this game on Ship 3 or 4.
