I find MilCSs more arguably useful in a peaceful game; in a game where I want a big army, I'm going to have to build barracks/armory/etc in at least 1-2 cities if I want a proper army, whereas in a culture game sometimes I won't bother building any of those at all, and will rely entirely on MilCS's.
Then what about making Patronage "flatter" as the Commerce tree f.e. meaning there are only tier two policies so you can easier chose just two policies? Would be a buff as well if you can get the Great Persons without having to invest 3 policies (right?).

Like going the piety route and being forced into rationalism??
