sion ult should demolish player-made terrain at full speed
It would be pretty cool if max-speed sion ult knocked a hole through player terrain. It wouldn't completely dispel it, just destroy any part that sion ran directly through.
Lower speed sion ult would behave as it currently does, though, and be stopped normally.
Imagine, the sion train comes plowing through anivia's wall and just leaves a shattered hole in the middle, or perhaps he turns jarvan's crater into a semicircle. POWER.
