please consider Imperial (Legionaries and Ausxiliaris) Roman Command Stes as well as Republican Roman Command Sets.
You have release a huge amount of Imperial Roman Sets (approx. > 20) and Republican Romans Sets (> 10).
There are some signifers and musicians in some sets and the real nice big box 907 (Imperial Roman Legion) with also some nice senior command figures.
But for this huge number of sets (even if you think about, someone bought only one set each) there is a real lack of command figures (muicians, signifer, Centurios, senior officers etc.) for battle, ceremonial march, etc.
I personally would buy a lot of these sets (cause I have bought each of your Roman sets several times).
... and I guess there might be some demand also by other collectors.
