Requesting help on Veteran Hunter Medal

People leeching kills for this medal irks me even more than leeching. I've worked hard to get to 45% on it on my Dawn Warrior, while people are simply tagging along with high levels to get it effortlessly. Disgusting. I'm tempted to get it on my DrK and abandon the effort on my Dawn Warrior so people can't just assume I had someone else do it for me.
