If they gave everyone of the Tenrou Team a battle role bigger than in the first movie, that'd take up a whole lot of time. There were after all quite a lot of people on Tenrou Island. Thus I think wanting both is a bit too much.

Either a more important/longer role or more people could work, but both is quite unlikely without having to take time away from the actual story... unless the movie is going to be overlength.
