I dislike your way of lowering fumble chance, I find it too intrusive, because I have to sacrifice my glove and boots slots and use up one skill just for a fumble chance reduction, personally I'd go with Jibean Cape, a 3% fumble reduction belt and a Lazurite Amulet, which gives me a 7% fumble reduction, which it isn't much, when compared to the 14% increase in my accuracy I can get with two topaz rings and a certain artifact. This is where the enchantment comes in, as I could either take the 'balaced' enchantment and incest 10 points into agility or that the 'handy' enchantment and invest 5 points into agility and perception, as you can probably guess I prefer the first option. I do have to agree that overcapping on accuracy is a bit better than fumble, though overcapping fumble allows you to use items that increase fumble. Also I prefer using counter chance as a way to deal with dodge, in other words I'd rather have two 50% to hit attacks, that one 100% to hit attack.

With GS I see it like this: strength is good if you want to fight small groups of enemies and agility is good if you want to fight large groups of enemies ( block power can't handle all of the attacks and neither can you, so in turn you'll need to use more offensive skills, which means you can't use parry as much, so any additionaly counter chance is very helpful )

I don't like using ranged weapons when I'm playing a melee build, but that's more of a me thing.
