Rework Sion E?

Sion has been one of my favorite champs to climb in ranked with and as such I feel as if he is slightly lacking power as a top laner. Against **Conquerer ** champs his trades seem to die down the longer combat goes, as he also relies on the proc from Grasp Of The Undying which requires time to get activated. His E is his best engage by far and sometimes even his best disengage which is vital in trades for him. The idea I'm trying to get behind is making his E "Roar of the Slayer" a Toss ability. An example would be comparable to a mix between Syndra's w and Galio's Old Q (Distance of Galio's old Q with the AOE of Syndra's current w upon impact in a smaller radius by 50). To where you can pick up a chunk of the ground/an enemy minion and Toss it as a skill shot. It's scaling can also be adjusted to having being a hybrid between ap/ad. Keeping its base as AP and allowing a small AD scaling to be applied along with its already in place ap scaling. Along with the fact that a lot of top laners are getting increases in health scaling along with garen's recent buff of 50 Armor and MR with scaling .33 per creep kill makes him a lot stronger, a buff to the Armor pen would give Sion a chance to actually do damage through other tanks and some bruisers as it now becomes a more complicated skill shot it is also rewarding so from 20% > 30% (the Slow would stay the same because it is perfect where it is at scaling wise).

Ex. (Mana Same)

60/100/135/170/205 (+25% AD) (+55& AP)

The reason I bring this up is because as he goes Sion is the Juggernaut of league I imagine him as having the ability to Toss a minion or throwing a boulder a part of his kit. His health scaling and current abilities all have a way of making him viable into a lot of match ups and with the addition of this Idea it makes him more rewarding to play.

(also open to opinions it's just my take on sion and what could change for him I think everything else is fine but his E can get a slight change of some kind let it be slight rework or scaling changes it is an ability that can be improved on)
