I'm looking to get into destroyers and I'm trying to decide which country to go with. I'm mostly interested in Tier 2 through Tier 5, but I'd also like to learn about the power rankings for the higher tiers as well. As far as gameplay goes, I'm looking to focus exclusively on using torpedoes. From what I can see, the Americans look the strongest at Tier 2 through Tier 4, but then the Japanese start to gain the advantage at Tier 5. Thanks a million in advance for any helpful responses.
