Agree! The AP scaling were honestly the biggest bother to me, as I felt like I always had a weird urge to build AP on him because otherwise the skills become terribly lackluster in mid-late game. I would keep the mana on his Q and W however, as I feel that these skills are still quite mage-oriented anyway and that going all-in with him might potentially be terribly dangerous as his skills would cost 20+% of his life to maximize his capability. Other than that, it increases his options of which items to choose since some mana items do work well with him.

I love the idea of a single-target skillshot stun, as his old one was almost exactly like Taric's. It should make his laning/ganking a lot more fun too :D

The new mechanics on his R are quite nice, emphasizing the fact that Sion should be tearing through enemy teams forcing them to focus him cause of his presence as well as the nice buff to MS to fix his mobility, because to be honest, Sion without Q can't really chase anything.
