Just playing and got the idea, can you make a map more extense, also make a building MCV, that gives the ability to pay for a buggy of expansion and make the one elected leader have the ability to build defense and barriers(destructibles), entering a menu in the MCV to see the map as in the RTS games(example the Kane´s Wrath), maybe even put him to place a few defense turrets on base or near expansions.
another thing i´m missing, is the weapons drop on enemies, example getting a sniper rifle after killing the sniper and getting it while being a engineer or any other...
