Why can every other ADC kill Jinx with just a Doran's Blade

But she needs either a gank, some long lasting form of hard cc, and/or 2 items to even have a chance of killing someone? She has the worst kit for early game dominance compared to any other ADC champion besides maybe Corki. Being slow with no escapes and some semi-hard to land traps/slows makes her a fairly easy target and a good champion to look for trades on since she cant match the damage by herself with just her Q (either form). Her Q (rockets) is good poke sometimes, but it costs mana and has slow af ATK SPEED before she has ATK SPEED items. The AOE helps but 20 or so damage is nothing really to worry about. Don't get me wrong, once she gets going she really comes online, but she is so item dependent that achieving that same starting level of dominance most other ADC's have by default is difficult to achieve.

Maybe if her W was more useful than just for the occasional last hit on a minion or attempted slow on an escaping target she would have a better early game. Being limited to 1 maybe 2 spells during fights is pretty hard to work with. Especially since her E has a long delay and her W is "first enemy hit", team fights usually don't see to many of them used successfully. Maybe add some form of execute damage on it for a lower AD scaling or lower its cost and CD so it can be used more often.
