Sona could use a little love

Right now our lovely lady is basically just a q poke bot. If you don't build AP, you're worthless. If you build AP, your team loses out on several useful support items. It's really frustrating trying to play her.

Someone mentioned that the focus of her kit should be auras, that she should be a more aura focused champion. And I feel that's the perfect way to take her. I had an idea earlier to change her w to a "heal over time" rather than an instant heal as well, as that would be less powerful than the instant heal but still allow her heal to be useful (unlike now, where I sometimes even level it last).

Sona also has a number of hidden power spots and scalings which are honestly harmful to her, as they prevent her power budget from being allocated to other places.

Finally, a note about the fantasy of Sona: She's a lady of music, I think that in order to benefit from music you should be listening to it for a while. If you listen to 1 second of a song, it won't have nearly as much of an effect on you as listening to 10 seconds of the song. So, I propose that we change Sona to be an "AOE Aura over time" champion.

So, proposed changes:

First, lets increase the radius of her auras by 50, and increase the duration to 6 seconds flat without any possible increase or decrease. This is just to make her feel a bit more...musical, and work better with the theme.

Next, lets change her q passive aura to proc on every autoattack while allies are in the aura. Obviously, the damage should be balanced accordingly, but this change would already work towards making her less of a q spam bot. It'd encourage Sona to have more extended trades while still allowing her to poke somewhat, which would be more interesting and enjoyable for all parties involved. I can also see some use to help allies CS under tower.

Then lets change her w to have AOE healing over time, without the shield. Basically, she heals all allies within her aura by X health per second, in 0.25 second ticks or so. It'd allow her heal to actually be strong enough to feel like it has an impact, rather than being healed by a measly 40-140hp or so. This would also involve more counterplay than her current heal+shield, as enemies can engage on Sona and her teammates while they're healing/in an aura.

Finally, we should remove the passive power increase on her ult, along with the AP scaling on her e. Both of these are sort of "hidden power" situations, or at least feel like it to me when I play Sona. I'd much rather have the power that those two grant as power elsewhere. I am not too sure about any e changes, just that the movement speed increase to allies should be for the entire duration of the aura.
