Lucian, Tristana, jinx put out insane damage and are easy to play mid late game.
And then you have champs like ashe who is incredibly outdated or are the above mentioned champs "toxic". Is ashe the issue here or the top tier adc champs?
Ashe is fine.
Most people want to go for mobility these days, they don't really care about utility until it comes to their jungle or support (Hello Thresh and Lee Sin)
Ashe is a fairly strong ADC, she just takes a different set of skills to know how to play correctly.
Ashe is just theoretically easy, but practically harder to play than the other adc's because she has a simpler kit. Most, if not all, other adc's have forms of escape or instant gap-closers. Ashe does not, and relies more heavily on her team to help her make plays.
Saying these champs require Master Yi level of skill to play is suggesting that Yi takes a lot of skill to play.
Lucian needs to be able to track his cooldowns and be able to weave his auto attacks in with his spells. Jinx needs to know when to switch her guns, and be able to lane her skillshots. Tristana needs to be able to kite her opponents, especially when her team doesn't peel for her, although Tristana is admittedly relatively easy to play among most ADC's.
I don't think these champs are "toxic", because the term suggests that they have unfair mechanics that make them unfun to play against, while these three champions have mechanics that may be overtuned.
Also, Jinx is by no means a top tiered ADC.
Ashe is actually fine, and effective.
Meanwhile Varus is complete trash.
Jinx is overall fine (though I think they would do well to make the contrast between rockets and minigun more stark). Lucian just has too much mobility, safety, and effortless trading, and Tristana's problem is more that they completely removed the mid game and she just gets IE and turns on immediately, and they removed the mana cost from her Q because they're idiots. If they brought back the mid game for carries you'd see the field open up more.
Basically the stupid shit they did with BF items is the problem, but Riot's itemization team has never had a clue.
Probably a little bit of both. I definitely dislike the absurd amount of mobility on all the popular ADCs. At the same time ADCs like Ashe and Varus definitely need a boost.
Ashe could use a rework. Graves too maybe? Ashe for sure. Sivir is one of those adcs too. Really only played at lower levels. I play her occasionally as she's fun as fuck. Bought the snowdown skin for her, too.
