You have Twisted Fate who uses his auto attack for W, same as Viktor Q, but Viktor gets left behind.
You have opressive Laners like Leblanc and Teemo getting an auto attack buff, while Malzahar’s and Vlads are complete dogshit with less range.
You have Ori who is dominating pro play getting a buff, especially considering she actively constantly uses her auto attack
None of these 3 champs are particularly destroying solo Q or pro play right now so there should be 0 hesitance to “overbuff them”.
Don’t you see? The tsunami of Vlad, Viktor and Malzahar ADC builds will drown the rift.
