Alright see this whole thing is really based on WC and AC, weapon class/armour class. Even if you have full armour on, chances are Ed's weapon class is still lower then your armour class, simply because hes prolly had a chance to level his Physical at SOME point and he has that RoF. So he will still hit you a good deal. Why you can't hit him is probably the same reason, because your weapon class right now is too high and he'll have a lower armour class, it may not look like hes wearing much armour but he is, not to mention he can blind you and has an upgraded weapon like Ghost said.
