hehe
am playing scots also right now ( and papal and... )
hehe
they realy do rule
But i have found a use for huge ammounts of noble pikeman:
i have them on bridges supported by archers and balistas,..
swordsmen give away under "real" cavalry or two-heander attack, SPEARS or PIKES never

And of course as for defending castles or citys... hehe, same shit: they just simply rule
