My only real problem with WG tossing Mutsu onto the premium pile is that she has nothing iconic about her. I mean, we're talking about a ship whose only claim to fame is blowing up and going to meet Davey in his Locker.
She's no Scharnhorst, Tirpitz, Warspite, Arizona, Texas, That said, she does at least have the distinction of having been fully built and having served, compared to Nikolai and Ishizuchi. But, still.
It makes me wonder what the next iconic premium is going to cost, as well.
Personally, I don't want lackluster clones, or ships with no history. The thing I love most about this game is the ability to play with history, and I want, need, to play with ships that had a part in making history. Mutsu doesn't fit the bill.
This is simply my own opinion, I ain't sayin WG is wrong for how they're doing this, or for releasing the ship. I just honestly don't know if I'm going to buy her. She doesn't "do" anything for me, personally.
