Soraka and the new mage items

Is it just me or does this look like it'll be good on soraka:

Cataylist of Aeons New Passive - Eternity: 15% of damage taken from champion is gained as Mana. 15% of Mana spent is gained as Health.

I mean every time she presses W, she's getting 1.5% of her max health back as mana as she damages herself to heal others. That alone is going to push the mana cost on her W to virtually nil. Then there's the mana spent thing negating a tiny bit of her health costs. Hey, I've survived fights with under 20 health before so it happens. Even if she wiffs a star call, she's still getting a little health back too.

Now add this to consideration:

Chalice of Harmony
Passive remade: Increases your Health Regeneration by 100% if your Health % is lower than your Mana %. Increases your Mana Regeneration by 100% if your Mana % is lower than your Health %.

So Soraka can now spam W and get a large health regen bonus if she stays back. Even better when you upgrade to athene's:

New Passive: Gain 15% of premitigation damage dealt to champions as Blood charges, up to 100 to 270 (based on level). Healing or shielding another ally consumes Blood Charges to heal that ally.

Your ult now gives everyone +270 health. Awesomeness.

Now if only Tear refunded her W's health costs.
