adc runes
I dont understand why you arent told to build pure attack speed runes like a jungler. you'll need the butchery mastery to farm, but its not that hard esp since the attack speed actually helps you just a little bit. The difference is about 15% attack speed which is worth 300 gold or more late game. If you werent building ANY attack speed, then full attack speed is worth 600 gold or more and its a big fuckign deal cause its like almost two whole components that you dont even have in inventory.
Edit: Only AS reds and AS quints. Normal Blues and Yellows.
