You are missing the problem . WG nerfed the 20 km torps to hell regarding a cryptic hard to find stat detectability . But the torps are still the stock torps . So the average player is stuck with them and might not even realize how bad these are . WG should have removed them instead . At the same time USN DDs got a huge buff while Shima got extremely situational hard to use 8 km torps which are harder to use than ever now witn so many ships having radar and usn DDs all over the place . So WG nerfed the only thing the Shima had going for it in the worst possible way and buffed all competitors . That was a brutal chain of overreaction that basically makes the Shima a quirky fun boat for thos who can use the 8 km torps but everyone who wants to win battles uses the Gearing or even the FletcherUdaloi .
