Soraka
You wanted to reinforce her as a healer, riot. In order to do this, you A) Took away her old E, the only "Mana heal" in the game B) Gave her a reward for keeping her allies low in the form of her passive C) Punished her for healing allies by giving her a 10% MAX HP COST on a heal she is supposed to spam. Not sure how that makes sense, thematically OR in balance. D) Made her unable to heal herself with W, instead making her rely on a slow skillshot to heal herself up again.
Ideas Passive: Same as live, but with her second passive incorporated. Q: Extended range, reveal, slow on entire AOE. W: Passive replaced by restoring half the hp you restore to allies as mana to yourself. No more health cost, castable on self for half the heal, cooldown standardized to 2 seconds. Has its cost and base heal increased by 10 for 4 seconds each time you cast it, stacking 4 times. Range extended by 5% for each 1% health the target is missing. E: remove the damn .1 second delay before placing it. R: Remove the delay before the heal. That Curtsy has gotten more champions killed than I would care to count.
