She's only going to be available during closed beta I believe. (can't remember where I read that).
Anyway, on topic: I'm disappointed that there are currently no battleships in game with AAA on top of their main armament, even if they add nothing to the stats. I personally feel they add so much to the look of the ships that used them. I really hope Wargaming will add these in. Even the ship in the loading screen clearly as AAA on top of one of it's main turrets yet no ships in game do?
Overall I like the Warspite, though my main issue is the 44mm max deck armor (This is so far off historical I half believe it's a typo in the game). Ffs even the Cleveland has 51mm and that's a frigging cruiser!
