Saiun is situational. When facing weak enemies, saiun will eleminate the chance of Red T which might save you from going into night battle for S rank. When facing dangerous enemies such as Re class, Red T can cripple the enemies' damage thus saving your ship girls from heavy damage in the pre-boss nodes.

The decision to opt out on saiun is usually made for clearing extremely difficult maps such as Events and Extra Operations. When regular farming, fielding one saiun is preferable.
