I didn't think I'd miss Kaiten that much...

Fine...
Having a buff ability that you "must" use every time before the actual skill is pointless, if Kaiten was a 1 min cooldown or something or had a situational effect like castin Iaijutsu while walking/instantly it had a point to exist.
You are wasting an off global cd casting a pointless buff to an ability every time you use it, no one ever used Iaijutsu without Kaiten, therefore Kaiten is a pointless Buff,.
You have to keep track of your Resources to always have 20> Kenki to be able to use Kaiten.

You're all high on copium because you liked the animation.

If Kaiten comes back, it needs the following changes:
1# Make it a 1min. CD, you next Iaijutsu is a 100% critical+direct hit, also remove the Kenki Cost.
or
2# Make it have a short cooldown ~30 seconds, remove the Kenki Cost & and make it "Your next Iaijutsu is cast instantly."

Telling me you didn't play samurai without saying you didn't play samurai.

Telling me you didn't play samurai without saying you didn't play samurai.

Oh?

Would you care to explain to the class when you should use Iaijutsu without Kaiten?
