I think 'horribly flawed' is a bit of an exaggeration. There are issues with how it currently is in the alpha; future updates (including the one going through QA now) will add features or make refinements, etc.
I don't particularly dislike it: but I DO believe that it might work best by COMPLEMENTING a saving throw (traditional) system, rather than completely overriding it.
It does not make much sense to be completely vulnerable once armor is out, and somewhat cheapens battle depth.
And thanks for the heads-up about a patch
