[GAMEPLAY] Bug Sion Q Indicator

Sion Q indicator is drawn on the same level of terrain where Sion is at that moment, but if he is casting his spell in front of a terrain with a different level of hight the indicator is not showed properly but is drawn however at the Sion level on the map. This is a problem for enemy team that doesn't see the spell, but only the effect, and for Sion that in some cases doesn't see if enemy is in or out his spell range. Here is a video of what i mean: http://youtu.be/GVd2TyjmFjE
