From that unboxing report it would seem the game comes with one Command Dial per unit... won't that limit your options with the Spearmen and Reanimates? You get 4 trays of each, potentially letting you field a 4 tray unit or two 2-tray units... but with just one Command Dial you can't do both.
I obviously haven't played the game yet and have no idea if it's a legitimate move to field a larger number of smaller formations vs. fewer but larger formations, but was curious. Maybe the infantry expansions could include an extra dial?
