Relatively easy to play with a starting 600!!! range. Better than most of the Adcs. That ult... seems like the best execute in the game. An As steroid of 130% at max rank. 10% bonus damage on her AAs with aoe? A late game Hypercarry that easily becomes a monster.
Why not?

If you spam rockets like that, you'll go oom early game, not to mention she's got the lowest base attack speed when doing so. She doesn't have any other projectile that can go past minion waves like Caitlyn/Sivir/Draven, her snare is relatively easy to dodge, and her W has a slight delay and is blocked by minions. She's got her weaknesses.
Besides, she doesn't fit every team comp, and other adc's are fun to play. Hell, Sivir has a few wombo combos up her sleeve and more teamfighting utility, not to mention dat spellshield. And Vayne in the current meta is both fun and strong.
I understand if you hate Jinx, but other adc's can be more fun.
weeaboomer1 votesI actually enjoy playing her and I find her extremely easy to play while being really strong. The only downside I find with her is no real good escape. Laning is still pretty easy, if I need to I can just switch to rockets to farm, it drains mana but manageable. Maybe her range should be nerfed early game, she seems way too safe.
AYYY LMAOKAI1 votesRIP pre rework Soraka, infinite rockets. 
IcyPepper1 votesThank god that doesn't exist anymore. ;~;
Laraso3 votesToo bad all the Jinx's I see have no idea what they're doing. They poke exclusively with their W, never switch to rockets to poke or attack grouped up champs, and like to throw out their flame chompers for no apparent reason.
And they tell me they main ADC.

<-- is she on the enemy team? Then, yeah, no. I'll play someone with a reliable escape, thank you though.
