Ashe And Sivir Are My Favorite ADC's

They've got simpler kits, an auto buff, a utility ability, and a n ult that is great in lane and can change a teamfights

They can both poke well and have an escape, Ashe with her ult and Sivir with ult, both of which can change the tide of a teamfight

I really like their simplicity, not because they're easy to play but because they're not going invisible and one shotting people, they're not chunking you for half your health just because you stepped on a trap under turret, they're not critting for 1/4 of your health every fourth shot either, and they're not dashing every auto (I don't care if Kalista isn't "meta", shes got an awful design)

I really like these simple adcs who are what an adc should be, simple but can change a game with the right plays, other examples of well designed adcs would be Lucian, Varus, Corki, Tristana, Quinn and Jinx

Just my thoughts, they can be though of as weak but they're the ideal balance of an adc, they only seem weak because of the dominance Jhin, Cait and Vayne
