But the thing about the 2 tier X BBs currently in game, is that they were the anomaly, not the norm, for the last generation of battleships. Even if they do end up with a Super Alsace in the game, there will still be a problem trying to find suitable tier X battleships for the likes of Germany, the UK and Russia. They had the H-class, Vanguard and Sovietsky Soyuz as the pinacle of battleship design. If the level of firepower is the deciding fact for tier X, none of those would rate any higher than tier IX, and those are just about the most powerful battleships ever designed by those nations. (Ok, Germany did have the H43/H44 concept, but that was very far out).
Vanguard was very close to what the Alsace could have been, and while Vanguard "only" had BL 15 inch guns, she would have been more that capable of matching the Yamato. She was, like the Alsace would have been, completed several years after the Yamato, applying many lessons learnt during the war, thereby making up for the deficiencies in firepower. One example is that the Alsace would most likely have received a very modern radar assisted fire control system, whereas the Yamato relied on optical fire control. It would have been far more accurate. Torpedo protection is as mentioned also a possibility of improving it, as torpedoes are one of the primary causes of premature death for battleships in the game
This link suggests that the 380mm/45 gun could penetrate Yamato's belt armour at the distances seen in the game, so in theory it would be able to penetrate and kill a Yamato under some circumstances:

Putting the Normandie based battlecruiser in tier 5 or 6 will also provide a nice break from the monotony of the line from tier 3 to tier 6. The Courbet, Bretagne, Normandie and Lyon and all 20-23 knot hulkers: http://s73.photobucket.com/user/Rengokuy/media/French/Gille-13.jpg.html
