German aircraft carrier Graf Zeppelin, tier VIII:
Torpedo damage increased from 4 533 to 5 333;
Flooding chance increased from 25% to 29%;
Bomb normalization improved by 5 degrees.
According to the analysis of statistics, the change to the Graf Zeppelin bombers in 0.8.4 was not enough to balance her against other tier VIII CVs. Changes to torpedoes will increase the total damage dealt by the CV, and the improved normalization will increase the effective armor penetration at certain angles and will slightly reduce the number of bomb armed against ship superstructures.
