Bring back Fervor Riot.
Pardon my French here, but quit pussyfooting around and bring it back, please.
You have an entire class of champions that are literally subhuman garbage now because they RELIED on that keystone to be relevant, all because of how you evolved the game and directions it's grown in. Top lane right now is literally be ranged, be a tank, or be useless.
It was obvious from the start that combing grasp and fervor was an awful idea so just bring the ladder back as was.
