All this talk of of warriors drilling through walls with swords makes me think of the french castle scene from Monty Python and the Holy Grail. All the knights charge the castle walls and Lancelot starts beating on them with his sword. of course nothing happened and they were forced to retreat.
Anyway now that I injected some Monty Python into this thread I'll go back to lurking.
(also I hope you see just how silly this argument is :p)
