Instead of making huge changes, Riot has developed a new philosophy of just making small changes gradually. What they find is that sometimes a small change is actually enough, and if it isn't they'll continue to make small changes until the champion or item is where it's supposed to be.
I suppose you could buff Warrior, but is that really necessary? Are AD-centric junglers really in a bad place? I can't help but think they're viable enough as it is at the moment. Tank junglers are just favored because the jungle is one of the easiest places to solidify your front line without risking it falling behind in lane. And now that tanks are actually viable in the jungle, pure squish setups just aren't as good in comparison.
I don't think reverting the nerf will really accomplish the kind of change you're hoping for and would just give unnecessary power to the item. Cinderhulk also feels fine after the nerf.
