Can we give back some bonus damage on Karma's W??

Raising the ap ratio from .6 to .9 was really helpful, the only issue is everyone and her mom can get out of the tether range. I don't feel like the increase snare duration is rewarding enough. Can we give her some of her bonus w damage back for landing the snare? For example 75/150/225/300 plus .2 ap ratio? I think this buff would be really help reward those few times when you can land the snare.
