I fully support this idea. On day one of the commendation system being introduced I had this amazing healer that did damn near everything perfectly (minimal overheals, DPS when viable, you name it), and because I was partied up with a friend, I couldn't commend him/her. It's really a shame when you meet a stand out player like that and you can't give them the full recognition that they deserve (aside from telling them in party chat).
