I'm not sure a commander is the way to go. There is a lot of crap tied up with the very concept of team commanders.
-Teams where no one wants to go CO going up against a team with a dedicated one
-Teams that have a shitty CO but competent players getting their asses handed.
-COs not listening to players
-players not following CO
-anything that makes them worthwhile makes it so that the team is utterly dependent upon them
-Abilities being used vs players that they have no control over.
COs would only really be useful for clan tourney play, which only makes up a small fraction of the overall userbase.
It just seems like a recipe for a bad experience. and for the record, no, i didn't like commanders in bf2/2142 either.
Giving squad leaders some abilities would be a far better call IMO.
