Not a bad idea, but yeah, it would wreck stat balancing. I'd rather see it applied to the actual chance to proc chakras by ourselves. Each crit that does not proc it, has a higher chance to proc on the next crit, and so on, until it happens. Then it returns to baseline.

That way, for every weaponskill that CRITS and does not proc Chakra, you get better chance on the next to proc it. The mechanic has merit (I remember it well from when I played mage! x) )
