Why ADC's have the Highest tendency to be OP
I'v been seeing this a lot, and while i do agree, let me explain something.
ADC's are broken in BOT LANE no matter what, because there isn't anyone that can go botlane as a Carry except ADC's. This is something Riot is working on right now, as stated by Riot Meddler in his updates so hopefully this get's fixed soon, that way we can see more Yasuo's, Cassiopeia's, Zigg's ect in botlane as Carries and an ADC or two won't HAVE to be broken every single patch.
I don't think ADC's are broken, if their strong BOT LANE picks, that's where their supposed to be and being the only class that can go Botlane right now reliably, it makes sense they would be. When they start to Dominate Top Lane, Jungle or Mid Lane is when i think their OP. Some marksmen should go to certain lanes, take Quinn and Teemo for example, or Graves and Kindred as other's, but if i see Miss Fortune Top at a 52% winrate, something is wrong especially if the playrate is high, that's when an ADC is broken to me.
This is different than saying Tanks are OP, or Assassins are OP, because both of those classes can go into several different lane's. Tanks exist in Jungle, Top and Support(Galio can go Mid) and it's obvious when tanks are OP because games will consist of 2-3 tanks instead of just 1. Assassins can go into 2 lane's and don't need to be in every team comp, so when games consistently have 2 assassins in them, that means Assasssins are OP. For marksmen it's the same but different, if we start seeing Bot Lane ADC's going into several other lanes, that's when we know for a fact their OP, but if one or two marksmen are overwhelmingly strong in Bot Lane, then it's not the entire Class that's OP, it's the champions.
