I thought it did before , thanks for explaining it <| sep |> well they kinda acknowledge the guilds ' s effort by actually spending time on programming and testing the content for such a small group of players . Sure raids have easier settings these days and most of the art is the same but tuning and testing of the additional abilities still has to take a lot of time . <| sep |> TLDR if you want to progress in new tier , ensure that you have Hatsuharu in your port right now . You will instantly skip Minekaze which according to prereviewers is an utterly awful ship in the new version of itself and instantly get T 6 from new tree . You will also get the new T 7 ship that will replace your Hatsuharu . I . e . you ' re getting T 7 from old tree and T 6 from new tree for the price of current T 7 Hatsuharu . They did not specify if you get to keep upgrades and ship ' s progress on new ships however , so you may only get the ship . If they let you keep progress on ship in the new tree this wasn ' t specified , you will get to skip straight to T 7 in the new tree . And you will be investing T 7 DD costs to get T 6 ship and bypass T 5 ship . So you probably should get it if you want to go up the new tree . Otherwise , you can safely ignore this advice .
