Before courage and the tank fiasco... We had the ADC damage fiasco...
Tanks were total trash and ADCs were getting a free ticket towards late game where current itemization allows them to pretty much ignore armor entirely

Well, we've seen what a pure tank favored meta and pure ADC favored meta can do.
Before we trash tanks again can we try a middle way between the two? Give ADCs something to do early game and make tanks actual meat shields even towards late game?
