Sion's Soul Furnace damage should scale with his Own Max HP

Soul Furnace: Sion surrounds himself with a shield that absorbs damage for up to 6 seconds. After 2 seconds, Soul Furnace can be recast to detonate the shield if it hasn't been destroyed, dealing magic damage to all nearby enemies. Bonus damage from the target's maximum health is capped at 400 against minions and monsters. The shield will detonate automatically if it persists for the full 6 seconds.

It's really silly, why not make it scale with your own Max HP instead. It not only makes up for his extremely unreliable kit but also gives him an actual reason to build tankier, rather than a detriment if he doesn't.

Don't get me wrong, Sions already nearly go full tank every game, but that's not because of actually getting any benefit out of it. It's because building him in any other way will just make you a burden, waiting to be carried.

Having your shield gain 10 health for each 100 hp you stack is not bad, but is not the best thing ever.

However, allowing you to deal 14% of your own Max HP to everyone around you is actually quite a good bonus on someone who is going to stack health anyway.

This change is just sacrificing a little bit of Sions early game for a slightly stronger late game.
