On the premise that no one wants to command because commanding simply sucks half the time, what's actually fun about commanding? What makes it an enjoyable experience? What would make players opt in to spend the round trying to get players to do their bidding instead of running around shooting people? For me it's just different, it's another part of empires to play around with. Building bases is probably the biggest draw though, placing turrets and walls to make impervious forts. Occasionally placing buildings on the front to help funnel your troops in a certain direction like lemmings in kinda neat at times too.
