Giving all ADC magic resist per level was a huge mistake
They were fine for the last few seasons? idk so odd to buff certain AD items and add MR per level, its the only thing that allows 
to go mid or top and his absurd amount damage in short trades. Giving ADC no MR per level basically forced them bot lane where they should be not because fuck diversity but because its healthier that way. The jungle was nerfed several times only a few viable options remain there is no reason to leave ADC as the predominate class thru out all stages of the game.
