Sacred Haven of Debauchery

By the way, this is quite stupid. A blockade + bombardment is obviously no better than a ground war; it's strangely implemented.

From a gameplay perspective, this is quite reasonable. Before, it was a terrible exploit that allowed you to win most wars even with a significant advantage on the enemy's side.

If so, I hope they at least increased the anti-bonuses for the bombarded. Didn't the defense weaken over time? But it was very slow, as I remember, and didn't help much.

If you bombard with a couple of corvettes, the defense will, of course, slowly decrease. It used to decrease quickly, and it still decreases quickly now. With zero fortifications, the defenders receive x2 damage, just like before.
