Jinx feels too weak

I can't put my finger on what it is exactly but she just can't keep up with the damage output of the other marksmen.

I know there are some weaknesses she's meant to have like being susceptible to poke and dives. But her bonus Q range doesn't feel like a true advantage until her Q is at least lvl 3 (just my opinion though).

She doesn't synchronize with the new runes as well as I would have anticipated either. Her kit itself is fine thematically but she struggles standing up to the other marksmen in lane in terms of damage.

I do want to get the opinion of other people on this though.
