How would it feel if instead of kaiten, shinten was gone?

Or, just remove Third Eye. Nothing about it fits the SAM fantasy, not even its animation.

The concept of third eye or inner eye is deeply rooted in the history of Kendo and other forms of martial arts with the idea of it taking in not only the opponent's face but also the opponents entire body. Enzan No Metsuke would be another derivative of it which basically means gazing at the mountain far away. You're taking in the whole picture instead of focusing on a specific thing.

This is why both in FFXI and FFXIV the concept of third eye is rooted in a defensive skill. So it fits perfectly fine within the fantasy of a samurai. So no, I'd rather they didn't remove a useful skill that not only gives a defensive buff against unavoidable raid wide attacks, but also gives me a dps increase by generating resources.
