What if Aatrox's Q softspots dealt less damage, but healed more from the damage dealt?

Most complains about his Q is that it can 100 to 0 most squishies with a single combo. What if we traded out some raw damage and put on some survivability instead? I mean, he was previously a champ with low damage output who relied almost entirely on his sustain and I do believe this concept is far more healthy than an oppressive laner who becomes a burst assassin later in the game because of how much damage he can do.
