Well, I'm seriously considering selling my Shimakaze and moving on to a different line of ships.  It's such a depressingly bad boat to get at T10 after grinding all this way.  I don't think I've had a single game that was any fun in this boat yet.  That's not to say I haven't had some decent performing games, but what a horrible boring ship this is.  If there's a mix of radar and carrier in the game, you just go hide in a corner for the first half of the game because it's so sluggish, you don't want to get dropped, and if you try and get close enough to anything to torp it, the radar or planes will either spot you for a one shot kill (really low health pool) or planes will spot your already horrible torpedoes so early that the other ships have a chance to make a pot of coffee, bake a cake and paint a picture of your torps before lazily dodging them as they blow your ship into little parts.   This boat is not fun.
