Scoring
Q: Is anything being done to help reward players who carry the flag/key/objective to their base but do not make the actual capture?
A: Nothing set in stone has been said other than they are working on rewarding players for teamwork and making it more rewarding to go after the objective than to stay on the defensive side of things.
