Vladimir max CD item vs all AD team comp

I recently had a game as vladimir in which the entire opposing team was AD. Now as vladimir, i find 40% CDR to be an absolute must. I usually get 10 from runes, 10 boots, 10 spirit visage, and 10 from WotA.

In the game vs the all AD comp though getting spirit vasage didnt really seem practical. I bought a kindlegem still and we were able to win before I had to upgrade it, but what should that last item be should the game carry into the very late game?

The way I see it there are 5 possible options.

1. Banner of Command - Magic resistance is wasted, but the health and AP are nice.
2. Zeke's Harbinger - Mana is wasted but AP, Health, and Armor are nice, along with a good passive.
3. Spirit Visage - Say forget it, I'm wasting a whole lot of Magic Resistance, but the health, and passive are still worth the slot.
4. Lich Bane - Doesn't really help vladimir get more tanky which can be a problem but still an option. Mana also wasted.
5. Ohmwrecker - Only Item listed without any wasted stats. Probably the tankiest option of the 5 when facing an all AD team comp. Late game, passive shoudln't matter as much however as champions begin to shrug off turrets.

In case it matters what other items I have to go along with this 6th item, my normal items look something like:

1. Ionian Boots of Lucidity
2. Will of the Ancients
3. Rylai's Crystal Scepter
4. Zhonya's Hourglass
5. Spirit Visage
6. Rabadon's Death Cap, Void Staff, or Liandry's Torment based off the opposing team comp.

I was thinking either Banner of Command or Zeke's being my answer, and Ohmwrecker if my team comp is squishy. What are your guy's opinions?
