Sion's Q indicator

Sion's Q has always been problematic in my opinion. I can understand casting it while in the brush and not being shown to the enemies, but the indicator that you can see is clearly not healthy for the gameplay. The video I found with a quick googling just further shows how much the indicator can just ruin your whole fight and how very little there is counterplay to that. The indicators should be there to aid you, not deceive you. If you want deceiving, use LeBlanc.
