Trying to climb
So Ive been playing adc for the longest time and my main champions are jhin and jinx, however the problem has now become that if i don't play one of those two champions, the chances of me winning a game significantly decreases, I recently made it to plat 4 and was hoping someone could give me tips on how i could fix this or maybe climb better with them, ive been told multiple times that my laning phase is weak and am unsure of how exactly to improve it. any help is appreciated, thanks again!
