After thinking about the new detection rules for a while, I noticed, that BBs now have the ability to stealth-fire.
Before I explain a lot, just check the yt-video I made:
The reason for this beein possible is easy, once you think about it. Shooting a ship that is hunting you, kinda increases your range, since he is sailing into your shots. It even worked better then expected, in the video Im driving the Texas somewhat in a straight line parallel to the König, trailing a little. When straight hunting, the range of beeing able to stealth-fire increases. Same goes for faster ships.
This last update questions many things, for example the Concealment Expert skill for Captains. Cruisers suffer most from it, imo. Why bother, when it doesnt affect my detectebility range when shooting?
Then think about the modules. Gun-fire-control-upgrades on DDs. Why would you want to mount them? f.e. Farragut will be spotted as far as 12,6 km with upgrade, 11,4 km without. There can be scenarios, where this matters. Lets say, there is a weak opponent, I dont know, Kirow with 200 Health, sailing at 8 km. Your DD isnt detected (since the 6,6 normal detection). Now there is a 2nd Cruisers full Health @ 12 km. If you decide to gun-kill the Kirow, you will be detected for the time the shells are in the air ( few secs.), Kirow sinks, you are hidden again. With the upgrade on the gun-fire-control, you will stay detected.
