Hey . Its been a while since I really put any time into league but I was a D 3 adc main . My best tip is honestly let the game come to you . Sit back and cs as best you can . Dont bother ever taking risks play hypercarries . Enough plays will happen around you that you will get free kills . Dont give up free kills . Also teamfighting is king as an adc . Always always ask yourself before a teamfight breaks out who are my tanks ? Am i behind them ? Who wants to kill me ? Who should I kill ? what CC is up to get me ? Am i the highest priority target ? . If you think about these questions before every fight you will fix your positioning and will wait for cc to be down . Finally , unless you are way behind , dont try to ever make the hero play as the adc . Thats not your job . Cs , do damage to their tanks , and take towers . That is your job . No highlight reel attempts if u want to climb
