Yesterday I was in a ok CT, I had entered the place with 2 others from my FC. In this CT we got a rather nice dragoon in our group that was very good and social, and if I could I would have given her a commendation.

So my suggestion.
If someone join as a group, let them give commendations to people other then the ones they joined with. I am not asking to be able to give to those I join with, but to be able to reward those random players that did a good job.
