Can we get some context as to why cinderhulk was nerfed?

If you went on any league data site (I always use champion.gg) everyone we'll see that devourer and runeglaive were already outcompeting cinderhulk champions this patch, with warrior a thing long forgotten, inferior in every way to everything else.

Despite this, cinderhulk was nerfed again, with this nerf being pretty big, bringing the bonus health you got from other health items from 25% to 15%. Adding on to this, randuins, the best armor item for cinderhulk champions was also nerfed. Because of its bonus health multiplier, you wanted to get a lot of health along with your armor, which randuins fit perfectly. You couldn't build sunfire because they have the same passive (immolate), so you would be completely wasting your gold if you bought it. But now randuins also got nerfed, which really hurts cinderhulk champions. buying frozen heart and thornmail would be a waste because neither would give any health for you to multiply with cinderhulk's passive. You've basically made it so that deadman's plate will be a much better pick pretty much all of the time, even if the enemies have a IE+shiv/PD adc.

Also prepare for runeglaive or a devourer jungler every game this patch, because those will be the only viable junglers.
