The main difference it makes is that it changes the ping from a reactionary action, to an offensive action.
It raises the skill floor, requiring you to know the general direction of the enemy and use the ping to collect more information when you have run out of available ways to gain Intel.
It gives her more counters because you can more effectively hide from the ping, but also means that if you are pinged, she already knows where you are and you need to move your ass.
It plays into her role as a "hunter", and will still be very good imo. Her kit is still super strong and tbh I think this won't change her all too much (her ping wasn't really a part of her kit imo, it was a crutch ability to spam whenever you got it, and this actually plays more into using as a tool rather than a catch-all)
