Remember the mission where you have to destroy the powder kegs of the enemy? Well, that just becomes ten times harder since you can destroy a ship instantly by ramming them once you've upgraded, and if you aim too well, all your cannon balls will hit home, and cause the ship to sink. You need to use all your strategy to get the ships where you want them, and slowly get them to reveal their powder kegs. Man! That was so damn difficult.

Also some of the missions where you have to protect merchant vessels. Sometimes while trying to save a ship, you accidentally hit it with a cannon since you upgraded your shooting range.
