I have to say, i am frustrated with the AI. Not because its hard, but because i can't understand why people say its hard.
ive created a single mission, much akin to the U-505 mission from Sh3. And quite frankly, im sneaking away, and im not even trying. Its just frustrating. Maybe the small adjustments i made (listed above somewhere) made them stupid, but the adjustments were minor tweaks.
I think im going to give up on trying to get the AI just right, im just not seeing what people are complaing about. Im trying to, i really am, but im just not seeing it.
