Well let's see...
Granted, this system doubles the rolling, but I wouldn't go as far as to say everyone would take it.
A 6th level fighter would have a maximum of 8 feats at his disposal. Naturally he would take one or two Parry Feats, if he chose to be boring. So he would look: Dodge, Weapon Focus, Expertise, Improved Disarm, Quick Draw, Weapon Specialization, Mobility, Spring Attack or he could look Parry, Toughness, Parry, Toughness, Par...oops out of Dex, Hmm... Weapon Focus, Power Attack, Cleave, Weapon Specialization. Both have their perks I guess.
I don't know, I'm not at my sharpest today, I've just come from a 30 mile bikeride (geocaching, great fun...) I'll leave this discussion to more able hands....
