endlessly stacking ad. mm. Maybe one day I can actually get through a tank without armor pen 10 minutes into a game. /s. But I feel like the attack speed rune is just going to take over, since you lose half your stacks if you switch targets and you have to do that a lot as an adc. Stuff's gonna be interesting and probably unbelievably broken for a long time. 7.19 is just around the corner, couple days from now so equip your ignites because Vayne is gonna be running wild
