So usually the new netherite armor give you knock back resistance right but in the official update of 1.19.10 almost every mob even having full netherite armor you get knocked back like it has lost its feature knock back resistance doesn't work and it's from a server so we both tried hitting each other to confirm this and yeah even having full netherite armor you'll get knocked back also i noticed diamond armor gives more damage resistance wearing full netherite armor a zombie piglin will kill you in just 6-7 attack with full protection enchantments diamond armor on the other hand zombie piglin can hit 8-9 before you die also having full protection enchantments
