The virgin Kaiten:
  • Comes up at fixed points in the rotation
  • No gameplay nuance
  • Button bloat
  • 25 gauge
  • Easily eliminated via consolidation into Iaijutsu, the only thing you used it on anyway

The chad Seigan:
  • Proper usage depends on boss timeline
  • Incentivizes using personal mitigation
  • Forces optimization and forethought
  • 15 gauge
  • Samurai confirmed 75% more braindead since its removal

The verdict is clear. You shouldn't want Kaiten back; any true Samurai player should be clamoring for the return of Seigan instead.
