Well, I doubt that his powers have a drawback myself, but he stated as weaknesses "Darkness" and "Light", and the smaller the details about weaknesses are, the more open I interpret them and counteract the powers accordingly. If you are still concerned that his abilities are over the top, then I ask Branch to tone him down.

Having a weakness to the other is pointless when you have control over both.  Either cover the area in complete darkness, which he can do, or illuminate the entire area which he can also do.  

The biggest problem is his control over life and death coupled with his ability to use ALL of his powers when pissed off.  So no one on the team has to worry about dying  or risking their life.  There's no sense of danger.  You can't beat him in a fight.  IF you manage to beat him up then you still lose after he gets mad and uses ALL of his powers.
