I want to propose the possibility to mount the Hydroacustic search consumable on Russian DD of higher tier. Here the module maybe should have similar stats as on a German cruiser.
In my opinion this would be a fair trade-off with regard to their bad concealment radius, +6km visibility when firing guns and low gun damage (as of patch 5.2) and make these DDs a versatile support vessel once again. Owing to the Hydroacustic search module they would regain their niche as a DD hunter and no further re-buff should be necessary.
What do you think?
