I got same problem, you need to touch all players so you get credit for their kills, that's wrong, you should get the kill if you are near.
I made a thread about this http://www.swtor.com/community/showthread.php?t=50977
Alot of comment that you should dps more to get kills as healer, please keep it away from this thread. A healer are a healer and not a hybird...
Is's also some issues with the absorb, you dont get protection points for it.
