Personally I would love to see cost for Crew/Ammo/ Provisions to give a little more cost a depth and strategy to the game.
Crew - simply a cost per man (the more men you use the more it will cost you)
When in port half pay
When on your ship full pay
This would mean you think more about the ship you take and keep an eye on your personal economy
Ammo - Why have unlimited ammo? If you are going out to hunt, rather than being able to stay out forever you need to plan your ventures and think how much ammo you may need...get it wrong and you may end up paying for it with your ship
Provisions - Crew need food and water, again if you are making a long sail (trading/ going to a PB/ heading to a nice PVP zone) you should plan for a long sail. make sure your crew have the provisions they need.
I think with these thing implemented it could give more depth to the ship you sail and the overall game experience
You could even go into adding perks if needed - 25% less pay/provision use etc
Just a suggestion and something I would personally like to see.
I welcome any feedback
Thanks, Captain Marchant
