QoL buffs for Sona

Sona's passive is important for harasing any laner. Especially her 3rd passive Q. It hurts alot. But let's not go that way.

I think that her 3rd W aa and 3rd E aa are too weak and it's rarely used.

Her 3rd W reduces damage output from the enemy for 3 seconds. But why? If you look at the W ability, it heals and shields allies. Why not add grievous wounds to it? It would be a perfect inverse ability. If W heals allies, W reduces damage output and reduces healing output.

Also, people rarely uses 3rd E because it's just a tad lane to use it. Even though it's 2 seconds, it's rarely used. How about increase the slow to (50 / 55 / 60 / 65 / 70%) (without scaling) for 1 or 1.5 seconds? People would use it for a jungler engaging.

Her E is also freaking terrible. 1% movement speed to level up. I mean who levels up this crap? Give it more AP scaling or more default movement speed. Reduce her self movement speed and increase it at later levels (10 / 15 / 20 / 25 / 30%) and increase her aura movement speed (8 / 12 / 16 / 20 / 24%).

Her ult passive is also too weak. Q has extra damage on her bonus magic damage. Let her have the Crescendo bonus damage on her normal Q.

W is fine.

Give a bit more movement speed to her E (3.3 / 6.6 / 10 %)

Win Rate is falling after the juggernaut patch and she needs some love, just like Nami did.
