i think is very good idea. Make for commanders boom and all squad booms at lvl.
ie. when commander have first or second lvl the all in squad gets 1% vitality or 1% power.
make different specializations of commanding (strong commander – gets power maybe stability, vigor commander – vitality swiftness, curse commander – more conditions and precision) Commander only learn when lead people win other. Those need to chose one way of commanding. It would be good for people playing in squad as well commanders
