The problem is it doesnt make sense. In actuality if i wield a onehanded sword and shield and you wield two shields- i can dance around you because the sword gives me reach. You wont be able to make an attack because there is no range to either of your shields. The same goes for spiked knuckles. My scimitars will cut your hands off before they get close. Unfortunately wow and diablo 2 make fantasy claims with claws and dual wielding daggers that dont have any realistics. Bruce lee vs. indiana jones. Lee goes for a kick, jones shoots him in the throat and laughs while he bleeds to death. Thats how ridiculous it is.
Thats another thing. What if you get surrounded, are you going to bash them to death with 2 shields. You will lose. This is not like the movies where the good guy wins in ridiculous scenarios like that.
If I understand you right, then what your saying is that no other option for offense should be offered than magic. As magic can be used as a projectile, then it would be usless to go at a mage with a sword sense they could just burn you to a crisp before you reached them? Your logic is flawed my friend.
Also, if you used one sword and one shield while I used two shields, all it would take to disarm you would be to grapple the sword to my body using my buckler (as that is one use of a buckler, if you know anything of real weaponry uses) and then my free hand could bludgen you to death with the other buckler as you try to release you only weapon from custody.
