Somethings I learn from the PBE playing Evelynn
First clear is a lot rougher, would suggest talisman over blade to start absolutely. Her health gets wrecked in the new jungle.
Hunter's potion might be ok on her but that first clear I really want to say ignore it and getting 3 pots is better in the long run.
Evelynn might need some help compensation wise since the recent nerfs with the changes will be harsh on her. The main issue for her imo, is her first clear. Past that she is will be the same but her first clear is literally really hard right now.
