I would like to see the radar (and maybe even the sonar - but in another way) to be more realistic as it was (which would balance it better too). In reality the radar made you knowing the position of a ship and the mark on the screen was bigger for big ships and smaller for small ships. What the radar did not show was the direction and the speed the ship was going. My suggestions:
- radar doesnt reveal the ship as it is seen by vision, but by its silhouette
- radar doesnt reveal smoke, which comes out of the funnel, so you cant see the exact speed of the ship, just approx.
- radar doesnt even show the shiptype, but approximately its size on the minimap (which is mostely compareable to a radarscreen), which means a high-tier cruiser can be bigger than a lower-tier BB oder a high-tier DD bigger than a lower-tier cruiser and so on
And now to Sonar: i do not think, sonar is too strong (maybe Z-52 is an exception with 2min 6km sonar), but as well as radar it did not show the ship by vision, but the position in water (same with torps) without any hints of speed and direction.
You could argue, that if a radar shows you the position of a ship, you can easier detect it by vision, because you know where to look for it. But if it is in or behind a smokescreen, you still will not be able to see the ship.
And of course, it is extremely strong, if the detection range of a ship is less than its radar range. I personally would prefer a radar, which increases the detectionrange by a part of its actual visibility range, which represents its size, which is responsible for its detection range (big shipps are easier seen by radar than small ones).
Suggestion:
US T8 +50%
US T9 +55%
US T10 +60%
USSR +80%
In addition can the maximum functional range of radar be increased to 10/11/12km for US and 14km for USSR cruiser, making radar more effective to detect low-range-detection cruiser and BBs. (everything of course also counts for BBs and DDs, which have radar ;) )
