Juggernog for Juggernauts, and some Tankaide
Edit 2016.08.26.10:15 -- Totally broken active removed
I think we should have items that can only be used by champions with "Tank" as a tag. This would have prevented the whole Sterak's Gage fiasco. Actually, making certain abuse-prone items only available to their intended champion classes would prevent broken builds. (I'm looking at you, Metagolem Fiora/Riven/Yi.)
We need to edit Titanic Hydra, Sterak's Gage, and maybe Warmog's Armor to include: REQUIRES TANK CLASS
Also, I wondered what an HP counterpart to Tear of the Goddess and the items that build from it would look like. Sure, it might seem a bit much to offer several items that give 1K Health each, but things are balanced out by the long build-up to get full stacks, and the fact that you wouldn't have to worry about assassins and fighters abusing them. Besides, tank supports would become fairly potent. Especially everyone's favorite mustache man, Braum!
And, what's not to love about supports being able to exterminate pesky junglers?
