Van Diemen

I have played some war patrols now in career mode, but I'm not very impressed by the AI destroyers. Today I attacked some task forces (some very weak ones that did only have small gunboats), but they where not very dangerous even when you attack them head on by using your deckgun! I also attacked a much larger task force with 6 destroyers, 3 cruisers and some small personal transports today, but after I had sunk the cruisers I wanted to sink the destroyers too. So I fired a torpedo, but this one turned at me (I know this happed during the second WW)! It hit me and I was lucky to be able to blow the ballast and surface the submarine, but on the surface there were those 6 "dangerous" destroyers! The destoyers didn't even attack me even though they where 600 meters away from me and I had no ability to escape because the torpedo had hit my engine room. The next 20 minutes my crew fired at multiple ships while repairing the damage on the surface to my ship. One destroyer ramed me, but not even one destroyer fired his gunturrets! I have to admit it was dark and there where high waves, but in SH3 the escorts whould have shot me to pieces and these escorts didn't do a thing even though they saw me ( I think ) because the aimed there search lights at me, but they didn't keep the search lights aimed on me like the escorts would have done in SH3. An other destroyer moved in front of my surfaced boat and droppet depth charges! I know that submarines attack at night because they where not seen so easily, but this is rediculous! Does they enemy in SH4 ever fire their turrets the way the did in SH3 and is this a bug?
