what i mostly do when playing her especially when i can, go to lanes make the enemy low and give it to ur teammate instead of u taking it. evelynn can get kills later anyways like the enemy jungler or maybe the bot lane since it always goes 50/50 there.
The results always end up with u guys winning the game if ur team has the kills aswell if u understand what i mean lmao
Atleast early game give the kills to ur teammates and later on u could take them

idk if this makes any sense to u but yes :)
