Not sure if this surprises anyone, Wargaming is now in the process of removing hulls like Bayern's WW1 hull, before the secondaries for all battleships were nerfed/reduced. Bayern's WW1 hull was seen as the best brawling ship in game and it meant any destroyer that sailed close to it was literally asking to get killed within seconds to minutes because it had effective secondaries. Then Wargaming decided to nerf all battleship secondaries into oblivion which even affected Bayern as well:
