Whouldnt it be a good idea to merge the skills "dodge" and "parry" und "evade" again and give them the common aptitudes Defence & Perception (you can only defend against what you perceive early enough).
As you still use Ag when dodging with Evade and WS when parrying with Evade, AG & WS would still be important to it, but Ag would be a little bit nerfed.
Of course, also my recommendation to use Per for initiative instead of Ag, still stands
