Kassawin nerfs

Let's talk about Kassadin. Near unparalleled mobility coupled with high damage and precise target selection has historically made Kass among the League's most resilient champions. Right now, our best method of 'gating' this guy (that is, trying to keep him from facerolling over the game) is by intentionally keeping his lane weak in the hopes of staving off what can feel like an inevitable riftwalking nightmare. While we want to preserve Kassadin's mobility-driven identity, he doesn't really have windows of vulnerability necessary for opponents to smack him in the face, meaning most fights are his to lose rather than any outplays his opponents can make. 1)reduce his damage only at first second and third rank would make more sense 2)retarded lee sin HIS INFINITE DAMAGE RETARDED CC DAMAGE START FROM MINUTE 0
