Jax needs a rework or just removed from the game.
Look at his kit. Its completely broken. Aoe Stun 2 seconds immune to aa. reduced aoe. 2x passives that give huge aa steroids. Gets scaling armor and mr based off his attack damage and ap. He gets tanky by building offensively.
The champion is just a joke. He doesn't even need to be fed to 1v2 or even 1v3.
