Make Kalista More Independent

I know the whole creation behind Kalista is her being tied to her oathsworn and her having empowered moves when the Oathsworn and her interact with each other. But for the love of GOD, make her more independent as an ADC. I don't know a single adc that has to heavily rely on their support just to barely make due and do what an ADC is supposed to do.

Revert the nerfs to her W, so that instead of her having more attack speed closer to her oathsworn, just set the percentage to an increasing value every time she autoattacks without stopping (kinda like how Jax used to work). And when she's solo, make it so her ult makes her invincible for a time but she can't attack or be attacked and she has more movement speed when chasing a champion. I want to be able to not rely on my support as much in game, just please make more more efficient and actually better as a champion.
