jax' weakness is that he can be kited pretty easy by carries and casters (the carries usually have spells like twitches ulti, or ezreal lol)

The ability to kite someone is based on that person's mind. If he doesn't want to come out of safety then he won't.

When I was new, I gave Jax a shot, and BOY did I suck it hard. He's not as easy as people claim, he just ramps up in stats very quickly if some one is foolish enough to feed him. I'd actually suggest Ashe or Teemo as a starter because they both have a passive skill, so there's less to manage and teamfights aren't as overwhelming. Sure Jax can pretty much roflstomp anything he comes across if he gets a good groove going by the early stages of late game, but in the hands of some one new who hasn't quite mastered placement and movement, not to mention gearing up, he's nothing but a punching bag.

He's currently a tank DPS. That shouldn't exist. It's way to easy for him to get ahead of everyone early game and nearly impossible to stop him after that.

Nerf his ulti or his dodge.
