My friend predicted Kai'Sa 1 Year in advance OR Riot borrowed some ideas from him...
Zaub: The Hextech Experiment
About a year ago, my friend made a champion concept and shared it with me. It was a Yordle marksmen with the special ability to be a split AD/AP champion. He also has two of the EXACT ability names in his own kit, Living Weapon (the W, albeit Kai'Sa's is the passive) and Killer Instinct (The R). Although the champions are pretty different, the base similarities are there. Freakish coincidence or what?
