I'd say that the E is broken. With it you could absorb Kayle's Shield, Morgana's Shield, etc.

I would also say that the R is broken as well. Assuming she has 2000 mana ( she'll have a lot more because she scales damage with mana ) she deals a maximum of 150 true damage per second.

Not to mention she also refreshes her cooldowns.

AND

She gets 30% Boosted damage..

AND

Vectors do True damage and there are FIVE of them.

I'd recommend changing the scaling from 20%/25%/30% to 5%/10%/15%

Remove the cooldown refreshing. Increase the cooldown. With Blue a 65 second cooldown can be spammed more often than Final Hour or Death lotus.
