And I don't know why!
I'm usually toplane, and I try to protect my lane and farm as much as possible since I'm not a star in that.
Beside that, I try to engage in teamfights as much as possible and try to damage my enemies.
Still, I almost always have the lowest total damage to champions of my team. Last game I just had 4,865 damage (on elin990 account) while the support had double my damage!
What do I wrong?
