New Sion build?

So how would the new Sion be built, both for top lane and jungle? And what skill should you max first? I'm legitimately curious because his kit can make him go in many different directions.

For skills I'm fairly sure you want to max either Q or W first, and E last. Possibly Q first if you are focusing on bruiser Sion and W first if tank Sion?

Item wise the offensive items I have been considering are ravenous hydra and trinity force and black cleaver (I think black cleaver would only be viable if you are getting hydra though because without that active he doesn't shred armor fast enough to be worth it), and elder lizard if jungling.

The defensive items I have been considering are basically all of the typical tank items, and ancient golem if jungling.

I feel like he is great as a tank with like 1 offensive item because he has a lot of CC, decent initiation and a % max hp scaling shield AND a % max hp damage dealing shield explosion. But I feel like he is great as a more offensive bruiser with 3 or so damage items because of his passive. I think if pros play him it will be mostly tank, relying on his more reliable skills, and cheese Sion would be more offensive and banking on his less reliable passive.

Thoughts?
