If you need Tenacity, consider getting CDR Glyphs + Merc Treads. This replaces the lost MR from runes, and a little bit of the CDR that you are missing from Ionian. You can also get 15% Tenacity from going down the Defense mastery tree. It's not a huge deal to miss out on 21 Offense; deep Offense is mostly just for carries, Riven gets most of what she needs from the first 9 points.

Sometimes you will want to do both; I have two rune pages and two mastery pages that I use for Riven, so that I can adjust my loadout and item build to fit the team that I am up against.

Another good source of CDR, if you are jungling, is the Spirit of the Elder Lizard.
