Yeah, that would probably be part of it. Also to be able to work well with others for the war. They won't be able to stay together for every battle, so working with others is important.

We just need to figure out what they would actually be doing. Just training has already been done earlier in the arc, so probably something like a mission without an enemy battle. Something to force them into working together for a period of time.
