I think Kalista's ghosts should not be seen through fog of war from a distance

The ghosts are really hard to get hit by and I feel like they should be buffed in terms of how they can be seen. I think you should be able to see them on your map/screen if they are within 600-900 units but no further. I am not biased because I don't play Kalista or even ADC. I just think her ghosts are too easy to avoid without being noticed and they really require some buff. Thoughts?
