why can't i play jax? is something wrong with what am doing or the champion?

I can't play the champion that i have 200k master with. i can't fucking duel nasus early game. i can't duel anybody early game. even with ignite. i can't do jack shit early game. why is his early game so shitty. the only time his early game wasn't shitty is when rageblade was strong. look i can play gangplank 10 times more effectively than i play jax. i have some 30% winrate with jax in ranked. and 60% on gangplank. i don't understand what am i supposed to do with jax. at all. he feels like a good pick against master yi and tryndamere. but thats about it. i can't duel nasus fiora. or even tryndamere early game. his late game is good but its not really that good because good luck getting 1v1s late game.

i like this champion but no matter how fucking hard i try i can't do jack shit with this champion. i do better with pantheon that i have only like 10 matches on and i have hundreds of matches on jax.

hes about the best at taking down turrets. but he sucks at everything else. he has the worst early game. of any champion. even kassadin is probably stronger early game. can we get some early game power. and sacrifice some late game power.

i don't like the jungle item at all on him since you do no damage. to squishies.
