So now for some actual feedback instead of the crying.
After playing subs far more than most people on the 3 tiers available I can say this,
1. ASW is still too strong you get hit by multiple waves soon as your spotted. The problem is the AWS is launched to fast from ships its instant giving you little chance of avoiding with any kind of maneuver.
A suggestion to fix this would give ASW a bit more flight time to target or reduce the range of ASW so your not hit by every ship in 10k range.
2.Torpedo homing is a joke if any ship takes any kind of evasive maneuver you miss your target most hits from subs come when your extreme close range or the target is under fire from surface ships, and is already committed to a turn and drives into your torpedo's.
Even the largest slowest German and IGN battleships can avoid your attacks if its a 1 Vs 1 you will probably not be able to destroy it unless you go extreme close range and make all your torpedo's hit and you will die to secondary fire or direct main armament hits.
3. Spotting is not working at all when you reach periscope depth you should be able to see everything around you but instead you surface and a destroyer or cruiser is 2 k away from you the spotting mechanic is broke.
Your vision should be instant once reaching periscope depth and not a reduced vision as the enemy ship can see you and fire before you even know he is there.
This is unfair as the sub is the most stealthy weapon of WWII you should have superior vision when at periscope depth also you should include the sound of ships propeller when surfacing if you are close to a surface ship to give you a hint.
4. Spotting from aircraft carrier planes fighter/bomber/rocket squadrons and fighters left by aircraft carrier its making the game unplayable as a sub captain its a JOKE.
Spotting a sub is a very hard task in WWII and specialist planes with crews were employed to do this NOT a fighter squadron or bomber squadron, they would not spot a sub unless it was on the surface its almost impossible to spot a submerged sub from the air without actively searching with optics.
You could fix this by making just actual spotting planes detect subs under water when within range as it would be in real life not random flights from CVs just buzzing round the map.
5. Dive time should simply be increased probably doubled to give you more of a fighting chance.
6. under water textures are great loving them
7.The German tier X model is absolutely RUBBISH the tier 6 and 8 give you a real U boat feel and vibe I love them please replace it as its a horrible model.
