Sion buff: Disruptive force of the Battlefield.

Alright, so I'm sure that Sion isn't as powerful as he could be, as someone who plays the guy. His cc is great for what it gives, but one thing seems a bit wrong.

Sion, lore and gameplay-wise, is a disruptive force on the battle field, which for his Q and W seems just right. But His E, Roar of the Slayer, doesn't quite fit the aspect. So I have two idea's, which could improve him as a tank, or a bruiser.

#1: Roar of Slayer could affect non-affectable units, pushing them back as it would and applying the slow effect. This would apply to things such as: Jarvan's Demacian Standard Orianna's Ball Azir's Soilders Makoi saplings and things like Cait and Nid's traps and teemo shroom.

#2: Sion is supposed to be a terrifying figure on the battle field, charging in head strong and such. What makes him even more terrifying is that he comes back to life when killed. This buff would relate to his passive where, when he dies, he'll fear any enemies within a range, maybe auto attack range or so, for a small brief period, lets say .5 seconds. This would allow his passive to actually benefit should he die in a team fight, and not just pick off a squishy, since they see that coming, and a slow just nullifies anyways.

So those are my ideas to see if Sion could be more effective. Criticism and comments are welcomed.
