The entire new rune system is designed to cater to ADC like everything else in the game
Even odd ADC like Jhin and MF have great options with aery and sorcery, and Ezreal with Klepto etc.........
Meanwhile unique playstyle mages like Azir and Kennen have been shafted once again by the lack of playstyle choices by being prevented from utilizing Precision by being forced to take attack speed early when taking Precision keystones.
