I can say that the period of the running of the test server is a little bit too short... The new skills should be tested more, especially that skill wich shows you the position of the nearest enemy. Is a little bit too overpowered in my opinion because it kills the dd's mission that now don't have an impact on the game like before. So let's say that you are sailing the Akatsuki destroyer, and you are going to capture a base. The enemies will now know from before where you are, and they can pretty much kill you easely, more often. That applies to all ships types in the game... Even that this "ability" was used in World War 2, I think that it will not make the game better. I like more to use my brain to make strategies and to guess where the enemy will be.
