I made a feedback thread of my personal experience with Kaiten removal and shared comprising suggestions as ideas that based off of it I'll share here, though it goes beyond just kenki management.

Note: I want Pre-6.1 Samurai over anything else as of now before they removed Kaiten if I had the choice

- Kaiten
Costs 30 Kenki, applies 30 seconds of guaranteed Crits to all Iaijutsu skills and Ogi Namikiri

- Meditation Gauge
Gauge charges increased from Max 3 to Max 9 ( for future changes as they promised )

- Hissatsu: Shinten
Casting Shinten grants 1 Meditation Charge

- Hissatsu: Kyuten
Casting Kyuten grants 1 Meditation Charge

- Hagakure
Converts Setsu, Getsu and Ka into Kenki and Meditation Charges. 10 Kenki and 1 Meditation charge each.

- Hissatsu: Guren removed
- Hissatsu: Senei
Senei keeps its original slashing animation and adds Guren's Line Slash AoE animatio, turning it into a line AoE attack. Keeps Senei potency on first target hit with fall of damage of 50% like Guren.

- Shoha II removed
- Shoha
Shoha changed to be a frontal Cone AoE. Potency of Shoha remains the same as original Shoha. Casting Shoha activates " Hissatsu: Seigan buff "

- Hissatsu: Seigan
While activated, user has 15 seconds to use Seigan to deliver a single target attack potency of ( original potency was 220 ) costing 15 Kenki. Buff is consumed when used. (i.e like say Ogi Namikiri )

- Meditate
Meditate will now charge Kenki and Meditation charges regardless of if you move or stand still. Can be used in combat while casting any other skill. Meditation will allow unlimited usage of Hissatsu: Seigan during Meditate state. Not moving will make the Samurai enter the original Meditate stance animation ( for nostalgia )

- Enhanced Enpi
Animation speed reduced, casts faster then regular Enpi.


So this is to give more interactions with Kenki, more depth, as well as more depth to the Meditation Gauge and combining some buttons to reduce that so called Button Bloat issue. I didn't do math on any potencies or how rotations would possibly be befitting or if this is balanced or not just spit balling ideas.

Note: Not ideal, not exactly great ideas, but if I had to choose between this and Kaiten removal, well i'd have it this way. ULTIMATELY I rather have Pre-6.1 updated SAM before the removed Kaiten however.
