Why is shield skill dependent on Agility?
Powerstrike - strength
Powerdraw (difficulty for bows) - strength
Powerthrow (difficulty for throwing) - strength
Shield (difficulty for shields) - ... Agilty
wtf.
You need to be strong enough to wield this axe, or that bow, or that javelin.
Sorry you are not agile enough to wield a huscarl shield.
Nope, stupid.
It is silly for realism, it is silly for balance, it is silly every way you cut it, pierce it, or blunt it.
