The High Aldwin
I know, I was just pointing out that by level 12, low to mid ACs don't come up that often.
And the point of the level is material when many games don't reach that point. Interest wanes, the game becomes more "super-hero"-like anyway, and such things are often expected in those games.
And I think the kensai is a perfect subclass to benefit in doing more damage with any weapon they chose as a kensai weapon. If monks benefit any where from damage, it should be to their martial arts die (which is why we bumped it up one stage as a house-rule).
Also, the barbarian still has many ways it can outshine a monk--this isn't a competition between classes, especially when you are considering the subclass of one (the kensai) and not a subclass of the other. As @TwoSix pointed out, the barbarian can reckless attack and completely mitigate (more or less) the -5 GWM penalty. The barbarian can also use a magic weapon, offsetting his own penalties as well. Sure, it might not be +3 but it will still help. Frankly, if the kensai is willing to spend 3 ki points I am okay with that personally.
All in all, I simply don't see it as being such a major concern as you do. Which is fine, as I said before it is a perfectly valid point, just not one I completely agree with.
