Kalista attack speed reduction when movementspeed slowed

So i guess you know that when Kalista is movement speed impaired her passive dash speed after the autos and q is slower. Therefore it takes her longer to travel the distance and she will not be able to attack as fast as she usually would. Now this has been ingame since her release (as far as i know) and frankly it's one of the main reasons why almost nobody plays her. I personally would think she should just travel a shorter distance instead of travelling slower. That would remove the issue while still upholding the fact that she's slowed since she won't travel the same amount of distance in a given time. I'd really like to hear your opinion on that. Is there any way one could get in touch with a Game Designer who could actually do something about it? I've noticed that it is fairly hard to get in touch with one, especially since her original designer CertainlyT no longer works there.
