Sonan eeds more power chords?

So I was looking at the newest PBE updates for sona and I started thinking about the consequences and how the players might adapt to them if they go live.

1. More auras. Many others have mentioned this and I agree. Now I feel it is a little odd because auras are invisible power and riot was trying to move away from them, but maybe they don't care anymore considering she now has flashy FX and is spamming stuff. I'm also wondering if this is because she hasn't been seen in LCS often enough for riot's liking and frankly LCS players would benefit the most from these changes... if she is picked. That's a big if.

2. Her cooldowns are going down at higher levels but not her mana costs. While you'll be able to cast your weaker spells sooner and you don't have to, I feel like a lot of people probably will try to use them as much as they can get away with. I dunno how that's going to effect her mana usage and itemization overall. Her base numbers are going down, her CD is going down more, and her mana costs are staying the same (so basically more mana used per second) so that leads me to thinking people are going to try to see if building her with more ap and mana to compensate. Would you start tear of the goddess before getting a sheen? IDK. It'd help with her potential playstyle but it'd be expensive for a support.

3. Assuming some people will spam her spells because that seems to be what riot is trying to push, that means more potential power chords for her. So if you are in AA range and you've got a power chord ready to go, you are going to use it. It'll also be up quicker because you probably bought a lichbane and an athene's. So this makes me think this is a primary reason to do these changes: riot wants Sona to poke people more often. Sona has always loved poking the other team, now she can do it faster than ever. I think riot is doing this because while her spell stats are going down, her AA bursts should be a little more frequent now. If you cast your spells as often as before, you are losing out in both damage and healing. However your Ult is telling you to spam spells more and the only way to make up for those lost stats and potentially higher mana burn is to make use of the more frequent power chord opportunities you should be getting.
