WOW Quest:A Valiant's Field Training (13592)  

As you advance from Aspirant to Valiant to Champion within the Argent Tournament, there will be dailies available for killing the Scourge of Icecrown. The Aspirant version requires 8 kills, the Valiant 10, and the Champion 15. Prior to 3.2, you could kill most types of Scourge in Icecrown for credit, but now only the Converted Hero counts. Thus, it is no longer possible to kill the same mobs to complete both the Valiant and Champion quests.
