When casting Nunu's W oppenents can see your snowball on the map, through fog

[GAMEPLAY] Nunu's giant snowball (W) can be seen by enemies on the mini-map

This one is fairly self-explanatory. Only the snowball can be seen on the map by the enemies, not the character. The enemy team confirmed this by telling me which camp I was at all game, and they were predicting all my ganks as soon as I pressed W.

I watched the replay of my last game from the enemy perspective and confirmed this is true. Heres the enemy team's perspective: https://youtu.be/MkH9IgKy7P0

I was using the Nunu bot skin. All of today's replays of my Nunu games have shown the W snowball on the minimap to enemies.

How to reproduce:

1.) Press W as Nunu 2.) While rolling the snowball, the enemies can see the snowball on their minimap through fog
