Dash/Snowballs a request for final balancing

I like the new changes and thankfully you saw the ridiculousness of the snowballs.. but at the same time it's still an issue of ridiculousness.

1. Collision - it should hit whatever terrain, teammate, friendly minion enemy etc and splat right there
2. Turrets need to be safe zones IE an aura of anti snowballs that snow balls hit and go poof. Having a tanky champ throw a snowball at squishy hiding behind turret, dash in kill squishy then casually walk out from turret still doesn't seem appropriate.
