Damn. Every time a new patch is announced, I get excited and click the patch notes with hope something has been done to address the issue I (and many others) have been posting about since day one. But nope. This really saddens me. Apparently, Ubi-Boat's report sent to the team did nothing.
Not that anyone cares anymore, but a good idea would be to differentiate boss stats from enemy stats in ACO. I like playing on hardcore difficulty. So I set enemy attack speed to 175%. However, this makes boss battles impossible. Not difficult - they're just unbeatable this way.
