S6 Masteries and utility mages who don't build AP

I think the S6 masteries are pretty cool overall. However, I've been playing some support Zilean lately (building mostly support items), and I've realized there aren't any good capstone masteries for him. Utility mage supports who want to focus more on utility rather than damage, e.g. Morgana, Zyra, and Annie, face similar problems, although they can get some value out of Thunderlord's Decree.

Can we have some some capstone masteries to help utility AP mages? Here are some ideas I had:

• +10% CDR and +10% active item CDR as a Cunning capstone mastery.
• +5% movement speed out of combat as a Cunning capstone mastery.
• +10% CC (not knock-up or suppress) duration as a Resolve capstone mastery.
• Some type of flat damage which doesn't scale with gold on a CD as a Ferocity capstone mastery (maybe 2% max health on a 30-second CD?).
