Poi is sweet. And deadly.

To make sub fast (to avoid sub node) you have both turbine and boiler, but it's worth it. Sub will draw attacks from half of enemies you meet and in yasen she can't get more than scratch damage, so she should tank all of those attacks. You can develop turbines using 100/10/200/10/BB flagship formula with chance of boilers, or with 100/251/250/10/BB formula for better chance of boilers but less for turbine.

Also it's worth upgrading Type 0 recon seaplane to seaplane fighters. It'll take some time, but they get a lot of mileage these days during events and are useful in regular maps like 5-1 monthly or 3-2 and 6-3 quarterly.
