@archaell Do you realize how ridiculously overpowered and unbalanced a 3 man sloop, 4 man brigantine, and a 6 man galleon would be? I can already solo a sloop efficiently, now imagine that but with 2 more guys and then sloop would be ridiculously OP. A 4 man brig would also be quite unbalanced as it would basically counteract all weakness brig has. A 6 man galleon would just be ridiculous as you would be basically unsinkable, able to use ridiculous amounts of firepower at all times, and you would just be able to make very stupid moves against the smaller ships and still manage to get out because of sheer tankiness.
The ships have been balanced around their current crew sizes and thus increasing (or decreasing) their sizes is not a good idea. I have a better idea. They make the server count able to have 12 ships, but you can spawn with 2. So you will still only be able to be at max 1/6th of a server (assuming you play fair, but this would actually make alliance servers harder). I would add in a 6 man and 8 man ship. The 6 man ship would basically just be a bigger galleon with 2 decks but the middle deck has 6 cannons instead of the top deck. It would be a galleon but with all the disadvantages/advantages around 1.5x better. The 8 man ship would have 3 decks, 4 masts (3,4,4,3 for the amount of sails on each mast) with 8 cannons on the deck below the main deck.
To balance these new ship types they would be for all intents and purposes unable to catch literally any ship which new what they were doing that was of a lower class. They would be large enough that they would require extreme amounts of coordination, and they would be quite easy to sink if you use tactics to avoid their broadsides.
