Ok, so I have had this one thing going in my head about "How can we add more ships to the game? How can we without making things unbalanced and with minimal effort for the Devs?
I came up with one... simpler way to add more ship types. Having our current ships to have different hull kinds, sail types, and much more. Ok, not the best way to describe it but... you know you could change your clothes that are drastically different? I am talking about that. Like, when you change your hull types, It can go from the generic one we have now, to a beat up looking carvelfor the bilge rat, or maybe to a frigate for Admiral. Or how's about something like May Flower on the Sea Dog's galleon, and something like HMS Prince/Sovereign of the Seas for the sovereign stuff?
With the sails too. One being torn, the other with clean edges, one built to last, and the last very decorative.
If I were to put it anywhay…
Basically, what I am getting at, adding new hulls and sails to each of the ships we have currently. If you want me to add images of what I am talking about, I can do that.
