I wish they didnt have perfect aim throuh loads and loads of plants and trees and through the ships.
I wish their bullets werent fired from their heads, meaning that when they are behind a rock and only their head is showing they shouldnt hit me.
I wish that hitting them with a sword would stagger them, right now they are usually quite unaffected by anything you throw at them.
I wish they were slightly less competent at firing cannons at small sloops going in full speed with wind in their sails.
I wish someone could program an AI that didnt have perfect aimbot.
Maybe they can simulate the same desync we have in pvp to make their aimbot less obvoius?
