Sion stuns himself for a brief moment whenever he hits an enemy champion with ult despite the fact that it only specifies that Sion stuns himself when he hits terrain,
Sion can't cast Smite while channeling his Q right now. I can't believe this would be an intentional change considering Vi can smite while channeling her Q.
Sion has a chance to bug out his cursor when casting and landing ult point blank in a very short window. The cursor will remain the same as if he were still ulting, not allowing you to move click with it.
No matter how much movement speed I have, while in passive form I can never seem to get close enough for that last AA, despite the fact that I have boots of swiftness, a zz'rot with a tower nearby, and a deadman's plate all contributing to it. Not sure if it's intended, but if it is, just...why?
