ST. Destroyer plating changes.
We're continuing to work on situations, when battleships cause too much damage with AP shells to destroyers. This happens when destroyers are at an angle and the shells arm inside the hulls.
One of solutions that will be tested in a closed environment is decrease of destroyer plating from 19 to 13 mm. This will only apply to tier X ships on the test, but might later spread to tier VI, VII, VIII and IX ships. Other specific protection traits, like Khabarovsk's increased armor, will remain. The plating change will make it impossible for AP shells of 380 mm and higher caliber to arm above the surface, which will lead to decrease in overall damage from AP shells to destroyers. Possibility of dealing damage with such shells if they arm in the water still remains, but it is pretty low to begin with.
Value of heavy cruisers in battle will increase, since 203 mm AP shells will stop ricocheting off of destroyers' plating. This will also affect Akizuki's 100 mm main batteries and battleship secondaries - their HE shells will start to penetrate the plating and deal damage to destroyers.
This way the amount of damage received by destroyers should remain the same on average, but the bulk of it will come from cruisers and battleships secondaries
重点：把X级DD的19mm船壳改到13mm（只适用于目前测试的船只），不过未来可能也会推广到6-9级，不过具有特色的东西比如哈日天的防火砖会保留下来
