Grow up. We live in an age where kids start having sex at 15 and know about it even earlier.
Something pointless. I don't play Kha'Zix but I feel sad about his nerfs. His AD scaling on his E got reduced to 20% from 80%. Health damage on Q from 8% to 6%. Damage vs monsters got nerfed by 50%, from 200 to 100. All this for 1 more second of stealth. It seems like they don't want him in the jungle anymore.
I'm glad that Yasuo's shield got nerfed though.
