Fubuki, Kagero, Shimakaze
The range of the torpedoes was generally reduced. To prevent the "torpedo spam" situations in battles and encourage players who prefer high-tier Japanese destroyers to switch to a more aggressive gameplay style, we also removed some torpedo types, whose range was excessive, from the modules available for these destroyers.
Fubuki: Type 90 mod 1 torpedoes were removed
Kagero: Type 93 mod 1 torpedoes were removed
Shimakaze: Type 93 mod 1 torpedoes were removed

The research and purchase costs for the remaining torpedo types were adjusted to keep the total cost in XP and Credits unchanged. Players will receive compensation for the removed torpedo types
