Sona update - What is she designed for now? Patch confusion! Discuss! Patch 6.14

So I was initially excited about the new patch update about Sona. After all, they open with a cool hook: that her CDR can be maxxed out to 60%.
But then, her auras are decreased, her power on Q is decreased, W and E increased. My expectation was that she would have a somewhat stronger heal and be more of a support.

Playing her, I found that she had much less early game power. Because the CDR is increased but not mana, she again has a big mana problem, and the aura CDR is not enough to help her teammates early game. I only got to mid game before I could tell.

This is my experience, but I am confused. Sona and other supports do well early game, so they can protect their carries effectively. Even if the Q got nerfed (which does sadden me), I was expecting that the W would be effective for at least a decent heal, or because of the CDR, could be used twice at least. But because the CDR decrease is based on her R, that means that she almost works like an ADC- late game is where she comes into her potential at the 60% CDR.

But that doesn't make any sense! I mean, if I was playing her as a straight mage, maybe. It would make sense to have this huge late game buff (CDR). But they made the rest of her kit so that she is a more passive support- in which case nerfing her AP ratios to this extent (and removing sommabulance from W- I never realized how much that helps) makes it so that she feels very weak in the early game, unable to protect her adc from tankier supports because the Q does not pack enough poke to make them go away, and the W does not heal them enough nor is the CDR effective early game. (Though, to be fair, I was definitely having a lot of mana issues and not accounting for my lack of power- since I usually stack a lotta AP for her to pack a little bit of a punch healing and poking early game, and because the CDR was not there early game- I finally got used to no longer having mana issues with her. Oh, joy, mana issues, my old friend.)

Of course, I could be totally wrong and just not have been able to play around with her enough. What's your personal experience with the new update? What have you found about the new way Sona plays, and her strength from early to mid to late game? Positive experiences? Negative experiences? What do you find she's stronger at/weaker at now? How do you intend to play her? Discuss! XD

addendum: with the mana problem... feels like they should bring back clarity XD

So is this a buff? a nerf? O_O

On second exposure- once actually getting there, the CDR is wicked awesome but i'm still totally confused as what she is intended to be XD
