Gameplay, Nidalee spears!

I just played URF and started getting chunked for massive amount of damage and getting nids passive on me. I realized that i could BARELY make out nidalee's spears because all that was there to see was the wind rushing off the tip. At first i was able to see them during early game, roughly about 15 minutes did i start not being able to see them. I dont really know how to recreate it and i wasnt recording at the time so sorry riot. :(
