Was looking at Ghaznavid List and noted Daylami - were 20 points - for C8, Shield, spear, warband, shieldwall, open order
or I could use troops from the Arab Caliphate list where Daylami are 17 points if you take them in open order and all the other attributes are the same.
The only difference I can see is that the Ghaznavid ones can have a light armour upgrade that is not available to the Caliphate Daylami when in open order, but there again they can have a throwing spear upgrade that is not available to the Ghaznavid ones.
Both would come from the Special Troops category.
Am I missing something obvious, or is this intentional?
