... Right before some people came to this page, Riven was considered a tanky AD caster. We used to talk about how Merc's worked far better than Ionian's, and that after her core (Which should be considered nowadays BT+GA+TBC), we usually discussed what was better for the last two slots. Randuin's+MoM reigned supreme in terms of defense in S2, and with the Randuin's HP buff it is now even better on Riven.

If you feel that you need to play defensively, get Merc's/Tabi+her core first, then Randuin's, Bulwark, MoM, Atma's or Merc scim, depending on the situation. It's far better than Warmog's, and regardless of the dogmatism that reings now on this page, it works great. Sure, getting full AD will work better sometimes, someothers getting tankier works wonders. A good Riven player always considers the situation and builds situationally, s/he doesn't gets always the same things.

All in all, even when playing defensively you shouldn't need Warmog's.
