Ahoy,
I myself rarely take the out flag, this is mainly because you have to go to the crow's nest after every session. Wouldn't it be better to also be able to change the flag in the Ship Customization Chest instead of just in the Ship Flag Box?
I know that the "real" feeling might go away if you don't have to go to the crow's nest anymore to change the flag, but I don't think this will be the case, because while sailing you still have to go to your crow's nest if you want to change the flag or want to make an alliance, I think the feeling of going to your crow's nest will remain.
I'm curious if you guys think this is a good idea or not.
