For those of you complaining about ADC's being too strong or too weak
As an adc main, I can say that ADC's do have a lot of issues w/ survivability and if you play ADC you are likely to get 1 shotted but I believe thats what makes it so fun playing ADC. Because they are so vulnerable, positioning skills, mechanical abilities (kiting and etc) and knowing how to build properly is what makes ADC's interesting to play for me. For those who are complaining that they are OP like Vayne or etc, they are THE most vulnerable ones that gets 1 shotted by almost everyone w/o their team. Every champion has their ups and downs and some have more ups than downs but it takes true skill to get around them. So git gud.
