You don't have space for Consumable Enhancement at all. PT is so important as the bots are ridiculously efficient at focus firing on a single target so you know exactly when to maximize your smoke consumable.
TGG because deleting cruisers at sub 9km is very easy in this ship.
Maximise reload and health stat for the remaining skills.
Mysore is very hard to go down in PVE especially with SI+SE and crawling smoke rotations. It specializes in deleting high evasion cruisers that troll your team BB dispersions with overpens and last second course changes. Effective sub 13km.
The huge advantage Mysore has over Leander, is 6 gun bow on profile as well as well as stronger rifles
