Champion concept: Maira - Architect of Time

So I decided to make another time-related champ because I think its cool. In the initial post there is no lore but maybe I will edit it. Role: Support

Edit: heres her lore! - Some say Maira created time, some say time bore her itself. Nevertheless, she used her special power to push herself above her opponents, and give a second chance to those who need it. But one day, Maira stumbled upon Zilean performing experiments in the clocktower; experiments that had intrigued Maira. She never thought that a mere human being was possible of such discovery. Maira was soon uninterested in Zilean's experiments, since it had taken him too long to find his power.

Still using her powers to defeat her opponents, she only had one challenge left, the League of Legends.

Appearance - She takes the form of a human, so imagine Janna, but different and more sophisticated.

Passive - Quantum Haste - Maira speeds up the effects oc Crowd Control on herself and nearby allies.

Q: -Reverse the Effect - Maira will reverse the effects of damage on an allied champion or herself and restore hp based on how much damage was received in the past. (CD - 12/11/10/9/8sec) (Heal - 25/50/75/100/125hp [scales with 30%ap]) (Bonus hp restored - 30%/35%/40%/45%/50%) (Time allotted - 3/3.5/4/4.5/5/5.5sec)

W: Altered flow - Maira will alter how fast or how slow time will move in an area; granting 40%mvmspd and 25%attsp for allies and -30%mvmentspd and 20%attspd reduct. for enemies. (CD - 19/17/15/13/11sec)

E: Disruption - Blasts an area leaving behind unused time, dealing magic damage. If in relative area, unused time will double the effect of her W. If cast in Altered flow, Disruption's cd is reduced by 70%. (CD - 9/8/7/6/5sec) (Dmg - 50/75/100/125/150) (Ap Scaling - 50% of ap)

R: Rewrite the Present! - Opens up a time area, where any unit in it will teleport back to their location and recieve 50% of their hp 6 seconds ago. (CD - 160/130/100sec)
