ADCs Are NOT Fine Right Now
Look, I'm getting tired of people saying, "Salty ADC mains can't do 'X' or 'Y' or 'Z' and come to boards to cry about dying" etc, etc. Look, the role is a complete mess and dependency on other roles. However, what I cannot agree with is for people to say that the role is "too strong" and "needs to be gutted". No, they don't need to be gutted. Do they need to be buffed? Heck freaking no. Get that shit outta here, I'm so far away from saying ADCs need to be buffed it's not even funny. Some could use some love and ADCs need a balance check for more bot lane diversity, but they are somewhat fine atm. That's not the issue.
I think some ADCs need to be toned down right now, IE: Cait and Twitch -- but for the most part, I think the main issue is ADCs itemization and the way they interact with Crit. They are going to need a complete overhaul. The role itself will only carry under very limited circumstances: IE, the enemy team has 0 strong engages or 0 divers that can effectively jump on the ADC. Other than that, the role will struggle doing anything remotely necessary to carrying teams. I've seen more games where the ADCs on BOTH sides of the team didn't even matter more than one being better than the next.
The games where ADCs are carrying are small -- especially in the Elo where I'm currently at. Maybe if you go higher up, they serve a better purpose. But as it stands, not just ADC, but botlane in general, is a scrap fest. It DOES decides who wins and loses games, but not the adc. It just depends on which teams Mid/Jgler or even Top laner is going to feast on the other team's bot lane.
