I play a bit of DBR, using normal scale, which I enjoy. However, I find the condensed DBR movement too limited, especially after using DBA 3.0. For this reason I think this version has some merit, where a 12 event game is desired.
I am not generally a fan of combined pike and shot elements, though can understand it within the constraints of 12 elements. However, I rather like the idea of using 8Sh to model small combined pike and shot formations. Well done! I think a 40mm deep base would add some additional space for the aesthetics. I also suspect that Sh should have a higher base factor against foot, and that 8Sh only gain the +1 against mounted. My views are influenced by Reid’s excellent “Gunpowder Triumphant”, which argues the increasing dominance of firearms on the ECW battlefield.
My intitial thinking, without playing a game, is that the dragoon factor is too high. I think you will see them too often in the open, where more often they would fluff around in enclosures on the flanks.
