From what I'm understanding yes, you pick up dailies to kill "X" amount of players or what not, in that zone, to receive "X" amount/type of reward.
People were complain atm, cause the FEW level 50's were just exploiting it, and say "hey, you kill me, I'll kill you, so we can just get this quest done to get my SOOPERDOOPER kill armor/reward"..
