Jax is the hero that I've played in closed beta. I've never touched any other hero but him, and I was known as I Play Jax because if I didn't get Jax I would dodge. (get the joke)
Jax was pretty OP in closed beta, and pretty OP at other points in the game, but in the end he turned out to what is he today, and I'll show you how to play him. Without trolling, since the last two Jax guides were actually there to hide my secrets of Jax.
It will be a straightforward guide on how to play Jax. Use it as a guideline and learn your matchups through experience.
