Honestly, Ornn's W should have never been changed into Max HP damage
We're talking about a tank who already has access to pretty consistent max hp damage in form of his brittle debuff.
His old W gave him sufficient oomf to go toe to toe with other tanks but his combination of CC, strong damage and being almost immovable in lane makes him extremely frustrating to fight for most other champions.
He either needs the W change reverted or actual meaningful mana costs so he has to back every now and then.
?? ATM he goes all tank because his W damage is absurd, he doesn't need more damage. The slow is OK, but trying to use the created terrain for his E is almost impossible against a competent player, as it is incredibly telegraphed
windwall blocks it, because that's ok lol.
