You know why we miss Fervor?

It's because it was the only real keystone that scaled damage with anything other than pure AD/AP (as in it got stronger if you bought non-AD/AP items). Sure, there was Grasp on HP, but that moreso gave sustain than real damage in the end. For Fervor, having attack speed or reliable hits meant you got more damage quickly. Plain and simple. And honestly, look at the Runes this season, and it's more of the same. Lethal Tempo gives attack speed, which means it scales best on champions with AD in their build. Comet, Aery, Predator, Dark harvest, Electrocute... All scale off of AD/AP. The rest is heals or utility other than another iteration of Grasp of the Undying, and Aftershock, both with light damage scaling since they're defensively scaling.

And then there's Press the Attack... Finally an ability that very slightly scales with attack speed, for once, and you give it team benefit to downplay your personal stats heavily. It's also (coincidentally) the only Rune that scales your base damage, which means that bruisers are almost forced to go that route.

We need some viable ways to scale our other build directions. Aery's sticking duration should be scaling with your cooldown reduction, or maybe Comet instead. I know you feel burned from scaling crit the last go at it, but it might not suck to make a keystone that is basically Draven's old passive (gain a DoT if you hit with a critical strike). And for the love of Ao Shin, get us something like Fervor back to make stacking AS feel more viable again.
