It's funny how champions like Talon get nerfed for seeing pro play,
But horrible cancerous champions like Sona and Katarina are completely left alone because pros dont like them. Especially Katarina holy shit, she can kill your whole team before you can even manage to get your courser on her with her teleporting everywhere then using zhonyas. She snowballs extremely hard the point where getting just a little bit ahead gives her the ability to 1v2. Not to mention she does this while having an extremely powerful lane phase. She manages to go even or bully it most champions early game by starting with fucking boots.
