A different stance on the Anivia nerfs

Currently, her ultimate costs 10/5/0 more mana per second on the PBE due to her high win rate. I feel that addressing a bit of the early game damage output but adding a bit mid to late game would be better than slightly increasing her mana cost on her ultimate.

Now I'm not asking for any big nerfs; I'm just putting my stance on what could be a potential change.

One nerf could be to change her E base damage from 55/85/115/145/175 (+50% AP) to 40/65/90/115/140 (+50% AP), but increase the Chilled debuff damage from (+200% damage) to (+215% damage). This would make the E deal from 110/170/230/290/350 (+ 100% AP) to 92/149.5/207/264.5/322 (+115% AP),making her mid game stronger (starting at 2 more damage after getting rank 3 on her E and 100 AP).

I'd like some responses to how people (especially Anivia players) would feel about these changes and if they seem fair.
