Darthmod is usually excellent in every TW game I've played, but I'm really disappointed in the Shogun 2 mod.
For starters, naval battles are completely broken. The AI will often build only bow kobaya and promptly sail them directly to the edge of the map and stay there. Often times, they'll get stock on rocks or sand dunes. This is completely broken.
In addition, the turn radius on a lot of ships is awful and way worse than vanilla. It takes sometimes 5-10 real minutes for a heavy bune to line up with another ship to board it, sailing around in awkward circles while it tries to properly line up to the position to board. It's easier for pandas to mate.
Cannon on ships have way too large a spray, resulting in hilarious instances in which Nanban trade ships miss at point blank range. Why are cannons so bad on ships? This is neither realistic nor good gameplay balance.
I now dread naval fights. They take forever and are completely broken. The computer cheats as well, using fire during rain storms while your own navy cannot do the same. Is there a way to turn the naval changes off for this mod?
As for the AI in campaign mode, it's not more difficult, it's just way more tedious. The computer abuses ninja, metsuke, and monks like crazy, but the worst is how the AI will march multiple, fullstack armies into your territory, then cheat by having every unit enter the battlefield at once. If only I could do that! I'd love to have 40 naginata samurai units in a siege.
I appreciate people taking their time to try to improve the game, but I am really baffled by this mod.
