I don't really think that raising it to 100% STR will make THAT much of a difference that it will be lifted up from rags to glory. Let's say your STR has a total of 50; and your weapon power is 15. Then, let's say for example that you're going to use a rank 5 Kagekiri. So, it will be like this (from what I computed, who knows, I might suck so bad when it comes to math. :v)

COMPUTATIONS AHEAD

So that would be
37.5
+ 15
+ 15
____
67.5

In Kensei's current STR percentage used; but should be bump it to 100% then we'd have;
50
+ 15
+ 15
____
80

And we all know that
80
- 67.5
___
12.5

and that is without factoring defense, and hell! That's the DAMAGE of their SKILL. No matter how offensive it may seem, does it not seem to be a tad bit. . .weak?

But either way, my point is, raising the percentage to 100% will not hold that MUCH of an effect. :v And maybe that instead of raising the STR %, we make some adjustment to make Kensei more appealing. (Just like what Dev said)
