All my proposed ideas include technology and solutions already present in the game btw, so there is no excuse for the current state of samurai over what I and many others propose, don't compromise!

You can source it looking at the Warrior Job Guide, as it's where I photoshopped a lot of that text into the example image:

Go to the Paladin from there to look at Spirits Within into Expacion, and check out the Gunbreaker's Gnashing Fang too if you're curious.
The only minor tech issue is Ogi is a weapon skill, while Ikishoten is an ability, and usually they don't chain a weaponskill into an ability...
HOWEVER, Ogi Namikiri goes from being a weaponskill currently into Kaeshi Namikiri, AN ABILITY, SO PSYCHE I GUESS.
Even then, if there was some BIZARRE technical limitation where Kaiten couldn't affect Ogi Namikiri, because the Ikishoten > Ogi / Kaeshi Namikiri chain was all made into abilities, that would still be completelyyyyy fine, I didn't even think of using Kaiten on Ogi Namikiri when I first started EW lol.
