The "Davy Jones" attack takes too long to hit the water for it to actually be effective. Unless it's being used on a stationary target, it's way too easy to move outside of the aoe. Aoe either needs to be increased or the cannonballs need to be sped up.
The visual clarity in large groups makes it very hard to see which ship you are.
With your allies being outlined and you not, it makes it very easy to loose yourself in a crowd and loose track of dodging and your cannon marker
As someone with some slight visual problems it would be awesome if there was a way to make your ship stand out a bit more from allies and enemies
