I also kind of wish you added a third map with a Port Royal/Tortuga type of map with buildings and everything and sides like the British Soldiers with their swords and muskets and Pirates with their swords and pistols.
Also I think adding a pistol could have helped the pirates in the Battle Mode but that is just a suggestion by other people and me in case you go back and change it! The Maelstrom map was good but I feel you made the ships too small (not way too small) and the reason I say this is because it seems literally all the Pirates and the Dutchmen Crew were just standing there waiting to be killed and throughout my whole experience on that map I did not feel threatened really since as I said they stood and waited. The Battle modes were 'iffy' since as you did mention the sides kind of just ball up on each other on opposite sides of the map which did make it easier for them to find but killing them was a completely different story since luring a few of them away would have worked but then I got the full brunt of the attack. I think it would have been an even more intense battle but nevertheless it was enjoyable! On the Maelstrom map, the Duel Mode on their was great and spot on since it was only Davy Jones and Jack Sparrow. Well I just got done playing in both modes (Duel and Battle Modes) on both maps and I really did like the Isla Cruces Duel Mode the best but I kind of wish you had James Norrington on the wheel.
