They're not only used as tanks or expedition derps, she (and most other subs) have other uses too:


 * Deployed to 2-2 or 2-3 to complete daily quests while still making a profit thanks to their low resource consumption, where sometimes they take too much damage in boss nodes to get away with B-rank so you have to sink 4 enemies (including tankier units like Wo or Ru) for A-rank. Without the Kai form's additional stats or cut-in ability, it can be tough to damage/sink those tanky units, reducing your chances of a victory at the boss node for the daily quest.
 * 6-1 requires half the team to be subs, so you'll really need her Kai'd for the additional stats and CI capability to pass the boss node.

Kai'ing isn't essential for the first point, but is definitely needed by the time you unlock 6-1. The increased repair time means you can't really use her for tanking anymore, but by that time it should be easy to have a maruyu in the fleet for dedicated tanking
