Team work will lessen the effect of unbalanced content, but that doesn't mean it should always be the sole remedy. ASW is a real hard counter to any SS (unless it's 1vs1 when the sub can just surface to avoid HH damage instead of crit diving). I don't like hard counters. Between nations, UK for example is supposed to counter KM in many tiers because of armour and KM's inherent weakness to armour. However, that doesn't mean UK will always win against a KM ship.

Same should go for SS and ASW. It's wrong that SS can die by just one salvo of HHs from a ship with a much lower level, and BBs of the same level shouldn't be as easy to kill by subs as some are now. I'd like to see sub gameplay become more interesting and fun, and that means buffing subs in some aspects, while nerfing others.

PS: The sense of NF devs is very limited, otherwise they would have properly balanced and tested the whole sub line, before putting it on the server.

A level 20 DD can kill a level 80+ SS4 and I don't see complaints about that, so why the whining?

Valid arguments like this will always be ignored by sub players that want to keep their stuff OP.
