I just had a potentially awesome thought, and forgive me if someone has already brought this idea up, but a stacking item that gives you armor or health on kill/assist I think would be glorious. Lemme know if im stealing someones idea but I would love if this item was at least considered
There WAS an HP stacking item that gave 15% damage reduction at max stacks. Nobody remembers Leviathan 
I don't think it's a great idea, tbh. Sorry mate.
Mejais and Sword of Occult are offensive snowballing items. Rarely purchased, but a tank version should not exist anyway. Damage outscales defense (or at least it should), but defense should not snowball out of control. Glass cannon champions who snowball have a chance at being shut down through cc and teamwork (it seems hard, but even a fed Riven can be defeated), but snowballing tank item? It'll make the tank further unkillable as they snowball, which even I who likes tanks being strong in the jungle thinks might be a tad too much.
I think a healthier mechanic for an idea like this would be seeker's armband. Some extra health and/or defenses per unit killed with a cap. Kind of like ROA too, now that I think about it.
we dont need another tank item in this already boring as hell tank meta.
Health? 
Armor?
