Now, this is going to appear a troll question on the surface, however it is actually an interesting thought..
Can you dual wield shields?
Now i've heard of this battle tactic in historical terms (I think it was perhaps Samoans or another similar army) who used a few of these men as.. well pretty much a 'tank' who could push the enemy back with one whilst covering his comrades. I only question this as I know you can recruit companions and to have a large Nord or such like as a big aggro stealer would be an interesting approach to dealing with a dragon..
Thanks
