Not many people play aragonesse, you wanna know why? because they are blind to their true power.
I have one word that makes any army good but theirs more than one:
Lancers: not many know it but Args have lancers the kings of cav
Alumgvars: best jav unit in game and good in cc
they also have good basic troops like your:
chivalric seargents and chivalric men at arms
and of course the pavise arbaslests

give args a try

bet ya'll lile them
