Bring Back Juggernaut
Cinderhulk is undoubtably a better jungle item for tanks than Juggernaut ever was. However, there are a handful of champs, generally bruisers like lee, jax, elise, etc, who frequently benefited more from the stats Juggernaut gave (a large chunk of health, tenacity, and CDR) than any other jungle item. Bringing Juggernaut back could be incredibly useful for these champs and help bring more diversity to the jungle pool and build paths. On top of that, having another tenacity item in the game always has provided more build path diversity, rather than frequently locking champs into merc treads.
