Tekagen really just needs to be taken out of Kensei's skill pool and made into an independent switch on the status screen. The whole point behind the skill is to hold back, and I don't see why non-Kenseis can't do that.

Not status screen please. It should be still possible to change mid-fight. So aka a non skillpool slot taking skill would be better. Aside from that, a general holding back skill for everyone isn´t a bad idea.
Is nice for RP when you are ICly crippled for some strange chaos events *cough*
