Evelynn Suggested Changes
She might have suffered indirect nerfs with cheaper 
and the new 
.
She struggles with early clears so i think of removing her shield from ult, and giving her a small one on her W.
W:
Additionally grants a shield of 40/55/70/85/100 + (20% AP).
Change her ult, she has problems to actually deal enough damage before she dies, so she ends up needing to build bruiser/tanky just to get through.
New R:
Affects an area around Evelynn for 5/5.5/6 seconds, slowing enemy champions for 30/35/40 %. 50% of the damage Evelynn's does during this effect is done as true damage and all healing done in the effect area by enemy champions is redirected to her. Enemies inside this area receive 40/50/60 + 4% their max HP (+1% per 40 AP) (+1% per 50 AD) magic damage per second.
