: Her slots get neutered and will be prone to getting emptied by heavy enemy anti-air. The ability to perform (O)ASW can be useful in some situations, but can impede her ability to conduct surface combat quite a bit sicne she prioritizes targetting submarines. Her Jet capabilities are nothing to write home about as she lacks the slot size to actually make them hit hard and survive reliably in heavy AA maps. That said, her niche role means it is better to keep her in her Kai Ni form unless you have the night planes required to make her useful in Kai 2 E form.
