Regarding certain ADCs

So in this post I see that OH, Sivir's getting some love, because she isn't the one adc that was used almost more then Jinx or vayne last season anymore, So they're giving her power again, okay but... What about Varus...He's a poke adc with a somewhat lackluster kit that can't always do much because he's immobile and can just get bullied in lane hard because he can basicly do pebble damage sometimes, And it's even worse for Twitch, If a beefy supp jump him, It's kinda over, Not like other adcs like Kog and Jinx's or Ashe doesn't have this prob, But Kog's Slow is better then his, Jinx's has a Root, Ashe can perma slow after a stun ult, While Twitch's slow isn't much and his Stealth takes time to make him escape..., Same with Varu's Ult, Oh Dw I'll just ult and root and escape, and try to survive the X seconds that they are not rooted yet even if I did just ult them... The R Buff on Varus and Q on Twitch was fine, But they need something else, Not mobility exacly, but maybe an escape or something to define them even more and give them some power and pressure, Bloody feels like a Yorick atm. I mean Varus' Passive is really not needed,, he scales with high AD, and his passive enforces that he likes some AS, his W is just passive like Ashe's old W/Q , when something could be added to it or his passive. Meanwhile Twitch is the only ADC with poison, like a bleed mech, But unlike Darius' his just scales with lvls and not even a tiny AD Ratio, and just feels linear, Because he'll just build bork ans sure shoot you from afar and hope on his E to excute you, while it has no % HP DMG for that , even if he does build Bork, That has been nerfed. It's just annoying to see other adcs get all the love while others just remain there, I thought this season was supose to be really diverse, when will they be viable enough for competitive without having them getting buffed/ Have a cheese move found out and made OP, Then only for them to get nerfed later patch because they're receiving too much play, Meanwhile I see a Lee Sin JG almost everygame. and that HIgh MS walking 2 Dashing, 2x dmg'ing High Base dmg melee can do so much and never gets punished or hurt for it.

Don't get me wrong these adcs like varus, Ashe , Twitch, Kog, aren't bad, but Jinx's is way more flexible because of her CC Dmg kit, ANd isn't really reliant on a specific SUpp to peel, or buff their strengths.

Edit: Also these 2 are the only ones Ik idk how Kog is(Still pretty strong with that %) or Ashe, Rip Urgot I guess.
