For the people asking me about a solo queue tier list, I'll just type a short one real quick:
Tier 1:
Lucian - Overall really strong kit, can be picked in any situation, strong laning phase, mid game and late. Good at snowballing and can take control of lane once you get a lead really easily. Has no real drawbacks.
Twitch - Decent laning phase, snowballs really hard, amazing late game, the only ADC to have map pressure past mid game due to his stealth and can pick easily, and his ult just tears through teamfights. However has no escape once his stealth is used other than slow.
Tier 2:
Draven - Extremely strong throughout the game, and can snowball because of passive, however lack of mobility makes him a risky pick. Ult can be used to snipe people across the map, and can use his E to interrupt gapclosers (Lee Q, Jax Q midway thru animation etc,) Hard to play mechanically, but gets easier to play after you learn how to juggle axes
Jinx - Decent laning phase, can snowball due to passive and ult, great mid and late game + really good at taking towers down. Extremely immobile however has a great self peel kit with w and e.
Cait - Extremely strong lane, decent mid game and great late game. Great at poking, and can snowball advantage by going to other lanes and sieging.
Tier 3:
Kog'Maw & Corki & Miss Fortune & Sivir - Don't have that much personal experience with this tier, but Corki and MF are both really strong laners, and I think we will see a resurgence of MF soon. Kog'maw seems to be decent as well with Botrk > Trinity. Sivir has a weak laning phase but can just push into tower all day and her ult is great for teamfights.
Tier 4:
Graves - Weak early due to range, but has a massive powerspike once you get bloodthirster. Can snowball pretty hard. Decent mid and late game. Easy to grab kills with Q R, and a well placed W can turn the tide of a lot of fights.
Ezreal - Weak laning phase, ok mid game and ok late game, one of the most mobile AD carries, easy to carry with if you can snowball early. If you fall behind, very very difficult to come back from and has a lot less damage than other ADs if you're not fed. Really fun to play tho
Vayne - Shittiest laning phase out of all AD carries, needs a lot of jungle pressure early or make really decisive trades, make one mistake and you're fucked, however if you get a lot of help and you get ahead then you can snowball, great in small skirmishes and 1v1s, has a lot of outplay potential, and great vs tanks. Decent midgame and decent late game. Short range sucks tho.
Tier 5 - The rest of them
tl;dr snowball
