I cant seem to play champions with ranged auto attacks
So, for some reason, whenever i play a champ with a ranged auto attack, i seem to do terrible. I dont understand why i do extremely bad on ranged auto attack champs. I mean, i tried out leblanc and got solo killed by soraka, but i won a 1v3 as zed. I mean, even katarina, i do bad on her but i know that i just need to practice her for a bit, but when it comes to people like ryze or jhin, i fail miserably. Can anyone tell me what the difference between ranged and meelee champs are? Btw for some reason i do well with kayle, even tho shes ranged
