Plz don't nerf aftershock in this way, tank will suffer.

Tank will be hard nerf by that. Aftershock is picked as a top rune against ranged match up and is core on jungle since they can't proc grasp and since they lack the tankyness to trade with other jungler before they get item will make them easy to be bullied. Just revert the aftershock to be a tank rune if the main goal is to kill the aftershock for other class (flat -> %value), removing the ap/ad ratio (even tho is a good idea) also would affect them too since some tanky jungle build some ap (Gragas and Amumu come into my mind).
