The question to ask is NOT "should secondary stats impact on the game be modified? or nerf?"

The RIGHT question is. Are secondary stats important enough to invest?

The ANSWER is YES, secondary stats are Skill Effectiveness stats. Very Important. primary stats are baseline Standard Stats. Also Important.

XD

Don't get confuse and think secondary stats should automatically be less important than primary stats. Just because they named it secondary.

Don't forget you go to primary school. Then when your done. Its secondary school that matters XD.

I was lucky, I'm new to the maths, I invested all over the place, i did not stack at first, but a veteran quickly pick me up and corrected me. it works so far.

A point on critical. Hit my right hand and I might lost my arm, hit the head or the heart and I could be dead.

A point on injury. Break the neck in one quick swoop. KO.

A point on stacking. In the anime. 1 Hokage level is truly skilled and experience enough to beat 10 average Joinin level, and.. we really want to think so XD.
