Nidalee is bugged.
In my last game the enemy nidalee was porting around...it was almost as if I was lagging but the other enemy champions were moving just fine as were my team and I. The wukong noticed the same thing, and I'm fairly certain he reported her for it. I don't know if it's a hack or bug, but she didn't seem to be hacking as the ports weren't really across map. It was more of like a flash's distance away from where she was originally standing on the screen. (without a flash animation sound or being in cougar form and pouncing)
