Cassiopeia's Hit Box
I think Cass's hit box should be shrunken by 10-20%. If you've ever laned against a Nidalee, Xerath, Ziggs, Vel'Koz or Lux you're familiar with just how challenging it is to dodge with her. I move as soon as I see a line shot coming but she gets hit even though her model is no longer in the hit zone.
