Lydia, The Banshee

I've always wanted to play a banshee like character in League. I know that could be considered one but she is a Fallen angel and i really wanted a true banshee so i came up with Lydia. Lydia would be a Support/Mage who rely on fearing and on AOE to make plays for her team and deal decent damage.

Passive: Fearing Scream

after casting 5 abilities, the 6th abilitie casted will fear every champion it hit for 2 seconds and amplifying damages against that champion by 10%

Q : Fearless Prediction

Lydia would leap onto her target and spin arround it for 2 seconds becoming untargettable and dealing damage to the enemies over time. She would then come back to her initial position.

W: Banshee's essence

Lydia place on the ground a seed that will stay there for 5 minutes and give vision of the area. If someone steps on the seed it will fear them and then vanish. (can stack up to 3-4 seeds)

E: Last Breath

Lydia would scream in front of her, damaging enemies in a cone and slowing them for 40% for 2 seconds.

R: Final Moan

After channeling for 4 seconds Lydia would send out a Scream that would kill any champion in sight Under 10% of maximum HP or reduce their magic resist and armor by 50% for 6 seconds if above 10% Max HP

This is just the way I thought of Lydia :) I hope Riot see it and makes a Banshee champion that woud look like this. Thank you :)
