Some Suggestions from a New Player Perspective.

Hi im new to the game and im enjoying it so far, but there's a few thing i think would help with making it more fun, other than the likely already mentioned suggestions about making it more like Black Flag.

4+ Player groups. Are there any plans to increase the party size to at least 4 players? 3 is too small and a weird group size. I know there are concerns of how to balance that but you wouldn't really need to as at the moment we just make a 3 player group, then one leaves the group and invites the forth friend and we just sail around a 2 groups of 2, and continue as normal as everything is open world and any one on the server can engage, so the issue isnt difficulty scaling at all and there is no need in a small party limit as everyone can engage and intervene / help in quests or open world events / bosses

larger map / server size surly the servers can handle more than 20 players? more to do, more event / missions types, sea monsters.

more fine control on how much the sails can be raised or lowered so its easier to navigate narrow streams / rivers. Even something as simple as just holding W and S but rather than instantly fully open or closed it opens them in a smooth motion, that you have a finer control over.

more gun mount slots on larger ships so you can have more options to mix and match gun types.
some ships have upper and lower deck gun ports so why not allow up to pick what guns are on them ports too.

also a cool idea would be small clans or guilds say 8 -12 players, you could add some new feature with like clan wars or clan based events that are both PVE and PVP so everyone can get something out of it.
