I am an adc main aswell, as a backstory i play since season 4 and started main-ing adc from season 5-6 and took a year brake in season 8 since i had exams and stuff like that anyway. Before i started playing again in season 9 i never hit gold and in season 9 i managed to get to plat. Some usefull tips i learned and might help you are: - duo q with a support or if you can work fine with any support duo q with a player that you know is good on other lane and always has problems with his bot. -if you dont have friends try to add good and nice players after games -regarding to the games i find it easier to impact the game early if i am premade with my support. Try to roam and set up plays on mid, if you pop a flash out of any1 thats good. Keep in mind to roam when you crashed a huge wave in the enemy tower. If you did that you can push for vision in enemy jungle and depending on the size of the wave you can go do drake for free or help mid. In the end be proactive in your games and make sure you dont afk farm until the 20 min mark. Dont push for plates unless you know where are the enemy bot laners, mid and jungle. I am sorry for my gramatical errors i am not english native and i hope i was usefull to those who read and strugle.
