While we're at it let's just give Samurai the Job Ability of "Game Over" where you automatically beat the mob as well as the game itself, and the credits roll in front of your screen.
On a serious note, I don't think Jishnu's Radiance could be justified for a C+ skill cap. Ranger makes it awesome thanks to the skill cap and thus freedom to gear towards it accordingly.
Samurai had a slight grace with Namas Arrow because of the massive R.Accuracy boost gained from its use, not to mention the accuracy already on the bow itself.

It would still be pretty overpowered, have you seen a SAM with a 5-hit Quint Spear? You can literally spit out like 5 WS in 10 seconds.
Also this. SAM simply gains TP too quickly to justify giving it an overpowered WS.
