I meant as in the mechanics of her kit, not necessarily the character.
Ashe is the FROST archer. She plays like a frost archer. She is fragile, but has abilities to slow and impede her enemies. She trades dmg for utility.
Cait is the sniper with long range and safety. She trades raw dps for safety.
Graves is the gritty ADC with a shotgun. He does better close range than other ADC's. He trades range for tankiness and dmg.
Kog is the squishiest but he also does the most DPS. He trades safety and defenses for range and dmg.
Lucian is pretty op, so he's a hard comparison, but he has mobility and dmg, in exchange for no cc and below average range.
There is far more trade offs than that such as wave clear, and poking that some ADC's get some here or there. Quinn was designed to have a strong all in, but a much weaker poke for example.
Jinx is le explosion XD so randumb. She has a bunch of abilities that have some synergy, but really just kind of exist on their own. There isn't really anything wrong with this, but everything but her Q is really generic. I guess you could say here theme is explosions, but not really, nor does her kit really reflect an explosions enthusiast like say Ziggs.
She has nukes, and cc, and range, and dmg. She has wave clear and tower pushing. She can poke and she can all in. While she has no dash, other ADC's who also give up a direct escape move get far less benefit. She doesn't really have a clear style like some of the other champions do. She just casually has AoE crits for some reason, and an execute ult that would be strong on anybody. None of her abilities really feel special or unique to her. Her Q is her most defining trait, but it's not really kit defining.
