Yeah, and unless this uber AI gets adjusted in the final, it's definately gonna need to be adjusted. Way, way too difficult. I think they just looked at all the AI sensor and detection ranges and doubled them all.
It'd be a damn cold day in hell when a DD could spot a periscope at night, during rough weather, at 2,000 meters and I only had the bloody thing about 1 meter out of the water. It was constantly getting submerged by each wave. Pffff.
We'll see tommorow (or is it today now?) I suppose.
