Did Cinder really need that nerf?
Out of all the things that needed nerfs this patch, this was probably the last thing that needed to be nerfed, especially after the other tank nerfs. Fact of the matter is, out of the top 20 junglers being played right now, 3 are Cinder users. And even of those, champions like Hec could go either way. It just seems unnecessary when Devour is by far dominating the top junglers right now, and is extremely gold effective.
While I'm sure this would have been necessary when Tank junglers were dominating the Rift, after the collective nerfs to most of their items which also gives a buff to other AD users, and the subsequent buffs to champs like Lee, it seems like the tanks are going to be more and more fazed out.
Maybe I'm off base here, but as someone who enjoys playing champions like this, it seems like kind of a middle finger to them, and honestly I'm not sure why. They were in a decent spot, and if anything, some of the devour users needed to be toned down.
