Player Commendation Rewards
SWTOR has a system exactly like you described and it never worked as it should. Players simply give commendations to their friends. Pretty sure same thing would happen in GW2, specially if players were to be rewarded for earning commendations.
Also, pvp is too chaotic, I don’t believe most players pay attention to who’s doing a good job or not, except for the score, which isn’t a good indicator of ones efectiveness in the game.
