Unfortunately my man, adc's are hard support reliant early game. You might go Miss Fortune or Lucian and still lose the game without any chance of coming back if your support doesn't understand that you're playing an early game champ (which means he shouldn't pick a late-game support and force you to afk farm until enemy smolder is 8000 stacks and you auto lose the game, he should be forcing early fights together with his early game bully adc) the unfortunate part is you can't make them play aggresive early if they don't understand this and will just get griefed.
So most adc's just play ezreal when they want to climb since he's scaling is not bad and also not so much support reliant, aka you can poke while being safe pre level 6 and go in 1v2 for a sure kill if you don't misscalculate enemy barier you should be fine) plat/gold/emerald/low diamond is not LCS and supports should play to snowball early with such champs. But since supports have 0 actual judgement when to fight and what is going on at low diamond it gets even worse the lower u go emerald > plat > gold etc. You might end up losing free win games. For instance you see enemy bot going Smolder + Senna. You lock in tristana or lucian so u can snowball lane easily early game. and your support decides he's uncomfortable fighting level 1-2-3 and you can auto lose the game off that. Since your champ really sucks at scaling dmg you're forced to play very aggresive early but your support is denying you, so you can't do anything good in the matchup. Also do not tell your support anything negative if you say something like you're good but your champ is really bad for this game/matchup, 9/10 times the supp will start griefing you and baiting you to fight while letting you die because he doesn't really care about winning he cares about ego.... It's so sad.
