A few battle-related questions

First, I wanted to know if a weapon's hit rate was 200, does this mean their attacks connect 200% of the time? If they're blinded, this would reduce their hit rate to 100%, which would make blind rather useless (only enemies with any evasion whatsoever would be an issue), right? Or I'm missing something out here? Does hit-rate affect anything else other than accuracy, maybe? Critical Hits?

I planned to reduce the hit rate values of most weapons to something lower so enemies that are supposed to evade a lot, actually feel like it. Or would it be more efficient to just make enemies more evasive instead?

My other issue I had, would it be possible to have "physical" magic attacks, ones that use the user vigor and target defense stats to calculate damage (I'm aware there is a check to make spells calculate physical defense)? I changed Blitz to do physical blows and the character that uses it has fittingly no magic power but a lot of vigor to use it, and it would hurt the character to waste all her vigor for magic.

Vigor brings me to my final question: I've heard many times that Vigor was a "useless" stat (one of them in the "What's currently hot" section before the site update). I wonder, is it bugged, or simply does work very little to be noticeable? Is there a patch or a way to make it more like how the Magic stat affects Magic effects? Thanks in advance guys!
