Plane balance will be changed relatively soon, any answer may become invalid tomorrow.

1. there is no sq leader with ijn
2. they are fast
3. run like a mofo, buy a new mouse, run like..
4. +12 will do, but if you have the chance go for elites

All in all, I suggest you level some divebombers.

1. Leave them as Fighters only if you:
- Won't have more than 100 vets and full experts (you get the most bang for the buck but the fighters themself are heavier)
- Want to max vet them (since FPs classed as fighter have more crew growth they can hold more vets they are a bit better than similar Ace fighters with full vets.

However if you plan on having more than 100 vets and are not swimming in cash to max vet them then class on time. The difference is somewhat small.

2. Thay're fast and have the most fuel.

3. Same as other CVs. IJN higher level fighters are fast enough to evade USN and scout while their bombers are notably second best.

4.People usually say it balances out at higher levels so i made my FPs +11 and they can manage against others (cept for USN) at higher levels.

ah... i see.... thank you so much for your advices...
