I didn't actually say "Russians ships are more vulnarable" - the point was: ships behave MUCH better when managed by computer. Now you also feel that, don't you?
By the way: was Varyag able to make your ships suffer? I mean - armored cruisers like Asama. According my undestanding of changes in 1.5 6" guns COMPLETELY ineffective against armored targets. So Varyag's shooting you mentioned - did it do any damage to AC?
