Weighing tanking stats has always been pretty much the same, If MR and Armor were higher on all items (we're looking at 200-300 armor on tanks and 150-200 on bruisers and 150-200 MR on tanks and 100-120 MR on bruisers for a full build), the amount of health necessary to tank wasn't as high so the value of pure health goes down. Health is an early game, and late game stat, Early on you want at least one health item (whether it was with armor/MR/neither depended on opponents comps and what kind of additional passive would benefit your build the best early) but after the first one, health as a stat kinda took the backburner as you would look more at items that would give you the resistances to better use that health, and finally around the 5th item health would become more powerful once you had the resistances to protect said health.
Now the changes Made MR items much more cost efficient but much less valuable since MR is plentiful you get diminishing returns much faster on it. Armor is a high value stat, but useless without health as auto's are mitigated but not hindered very much by armor until you've got a lot of it. Early health is now much harder to access in the necessary amounts that are needed to tank more than 2 people, but that 25% bonus kinda throws that out of the window. tank junglers would have much higher health pools early, and would still be just as oppressive as they were before as they can look at more powerful armor items that give less health as cinderhulk would simply cover what the nerfs were intended to do.
Just because the devourer changes overshadowed cinderhulk, doesn't mean that after they nerf it people won't go back to cinderhulk. Both items were just overtuned, and riot gave the scalings a nerf rather than the base stats their rushed items got. this way junglers do still have very good items early on that help them late game, but don't completely dominate because the scaling their items gave them were too strong. Also the New Atmas
is extremely powerful when paired with cinderhulk and the higher health items, and together with strong engages and pretty high base damage as it is, tank junglers are looking to make an even stronger second coming if cinderhulk wasn't nerfed.
Sorry if the post sounds super snarky. Not intended to be that way.
