Thoughts on this:
 * Your passive is a very complicated way of reinserting Sion's current passive. Fury here is functionally equivalent to health, as it's a resource that doesn't get depleted other than by taking damage. You would be better off just listing this as maximum health gain, particularly as it's also forcing you to deprive Sion of mana costs: past level 6, this guy gets 50% free permanent life steal on demand. If he has no mana costs to force him back to base, he'd be able to stay in lane indefinitely, even if he's under heavy attack. The Fury gain on champions also adds to the complication, and potentially adds a snowballing component (Sions with a killstreak build up massive amounts of Fury, Sions who fall behind don't increase their Fury nearly as fast). It would be better to just double the gain on large monsters, large minions and champions, as with the current Enrage.
 * Axe Charge is functionally good but thematically weird: Sion's a big slow zombie, and this ability lets him dash around on a relatively short cooldown. He needs sticking power, but a gapcloser doesn't look like the most appropriate way to achieve this.
 * Death's Caress has no indicated duration for the shield. The shield restore is also potentially unhealthy: shields are meant to be short-duration boosts to tankiness, whereas this means you could technically hold up your shield forever. The maximum health scaling looks good, but would work better if you changed his passive to give him his old permanent max health increase: with that buff, you wouldn't need the restore.
 * Berserking is a bonus that has very little actual gameplay attached to it, despite granting potentially massive bonuses. I think you should change this to something else, especially as the CC immunity also overlaps with the slow immunity on his Q.
 * The current Cannibalism has a lot of problems: it's so ridiculously powerful it forces Sion to have no real sticking power, it lasts for too long and has an extraneous ally heal effect that most people don't know exist, even after playing with Sion. While your own proposed ult at least doesn't grant attack speed, it also has problems: the main problem here is that it essentially exacerbates the current ult's problems, making the steroid last potentially ad infinitum while making it extremely hard for Sion to stick to targets. It also forces Sion to fight his own kit rather than his opponents: true interaction would involve making this steroid counterable through reactive play, but here it's only kept balanced by self-imposed debuffs, which is not in itself interactive. You said you wanted Sion to be a lifesteal tank, but lifesteal tanks work as such because they synergize well with the lifesteal they build. Here your kit just gives Sion tons of free lifesteal that is itself hard to play against. You'd be better off finding a completely different ult for Sion, but also orient your kit so that they either work well with Sion purchasing lifesteal or scale with lifesteal directly.
