Yeah, it seems to be a lot more variable, but from what I read there were a lot more shot than pike in their numbers (I corrected my previous post where I'd typed pike heavy instead of shot heavy). So have a few "standard" units (Ruperts, Kings, Yorks) then a few shot heavy ones (various regiments brigaded together) then some commanded shot (e.g. the Shrewsbury foot).
Means the Royalists can lay down a bit more fire but are likely to not be as good in melee. My NMA are mostly "untried" as well so variable based on whether they perform well or not (at least for FK&P, other rules will use slightly different stat lines).
Should hopefully give a nice balanced game between ragtag veterans of the Royalists and the professional but inexperienced NMA.
