Now that the event is over and the Argent Tournament grounds have phased back to normal, I found that one of the vendors still accepts Argent Commendations for ilvl 100 gear. My DH has enough Darkened Scourgestones to trade for one commendation, and that's literally all I need.

Is there anyone on the tournament grounds who still accepts the stones to trade for commendations? Or are the stones now just vendor trash? (the item tooltip has not turned gray, if that means anything.)
