Stat bindings: A jungle tank item
Tanks - champions that build magic resist and armor - need a better jungle item. Cinderhulk is not a tank item -- it gives damage and health, which are part of the juggernaut stat bindings.
What about giving tanks something like this: Enchantment - Hexmetal Shielding Chain vest + negatron cloak + 200g 40 armor 40 magic resistance +20% bonus armor and magic resistance Unique passive - Heavy Metal Poisoning: Upon receiving damage, the responsible enemy unit is poisoned for 3 seconds. Poisoned enemies take magic damage per second based on your current armor and magic resistance as well as have their attack speed slowed. The damage is doubled vs monsters.
I don't know what numbers are best, but I do know that this item works for tanking instead of juggernauting. In team fights, it encourages tanking instead of just being there.
