As someone who likes navy combat and knows a bit of history something bugs me since I played WoWs. Could someone(or the devs) explain to me why Tatsuta is "Tatsuta Class Light Cruiser"? According to history, Tatsuta was one of the two ships from Tenryū-class cruiser http://en.wikipedia.org/wiki/Tenry%C5%AB-class_cruiser She was newer, yes, but ultimately the ship class that Tatsuta comes from was "Tenryū" not "Tatsuta Class Light Cruiser", what was the decision about making Tatsuta class in World of Warship?

Alright I see ^^ thank You both for answering that, tho it still kinda surprised me as Tenryuu was first (According to the Myoukou class example), well I guess one day Wargaming may share with us why they named it like this. OvanBruce aren't You also on Himeuta forum?
