Change/nerf aftershock to make it less abusable

Aftershock in itself is an issue in many ways and has been one ever since its creation. I play thresh so someone might want to say shut up here but when champs like Lissandra and Galio can abuse it the way they do then something is wrong with the rune imo. I do wish that the rune could be made so that u shouldnt be able to oneshot ur opponent and stay relative tanky to boot. This is a major issue in some champs that abuses it in bad ways. Im all for ap galio and Lissandra but the fact that those 2 champs can do what they do isnt healthy. Galio atm is alot of reward but very little risk due to the fact that u got the aftershock training wheels constantly on him same with lissandra. Rather Lissandra is at the point there she is almost played only due to the fact that she can got aftershock. Yes people who like to play fun builds goes electro or dmg trees but aftershock will Always be the better option. I wish Riot would decide on what Galio is supposed to be because what he does now is basically everything u need.
