In my game I had issues with a HUGe pirate fleet sitting on my trade routes, which i threw my entire fleet of 6 3-rates,6 4h-rates and a 5th-rate at to try and remove them,but there galleon and flyute fllet was nastier than expected and smashed my fleet, Apart from that Portugal seems to be surving the war with spain someone and is being a rotal pain with blockading my trade routes,after they declared war with me and I brought 10 hindu musketters over from mysore which I had just taken and smashed them,not expecting them to hang around that long..
