Hey CaptainTeddybear,
The IJN line as another captain has already said does have slower turret traverse than other lines but the playstyle of the IJN BBs is designed that way. They are designed to be a mid to long range sniping style of BB where in theory you will not be traversing your guns as much. The Soviet BBs are designed to be a more brawler style of BB where you will need to shift your guns more frequently from side to side. You also bring up the Georgia and she is kind of a hybrid with accurate guns and secondaries that make you want to close the distance.
Tips for Yamato:
Always pre-plan where you want your guns before you commit to a movement because of the slow turret traverse speed.
The Yamato is not designed to a brawler, if you get into brawling range with another BB and the other BB knows what they are doing they will do a "drive-bye" and citadel you under the turrets.
You want to keep enemy ships at mid to long range so you can take advantage of the accurate guns. The Yamato is quite tanky with the combination of deck armor and torpedo protection.
When facing a Kremlin, aim for the superstructure if they are sitting bow on to you. You are more accurate with than them at range. Remember you can also overmatch 32mm armor and if I am not mistaken that is the thickness of the Kremlin bow =).
These are just a few tips to playing the Yamato correctly but if you are brawling you are playing her wrong! If you are going to brawl make sure your turrets are prepared and you destroy what you are shooting at. This is where other BBs gain the advantage if they can survive taking the damage and get around your slow turrets.
Good luck playing the Yamato!
