Well, I have been max rank for quite some time now and have played against my fair share of Evelynn players.
All I am saying is that an Oracles will put her ganks to an end. How is she supposed to sneak up on you when you can clearly see her running towards you lol?
BTW, I only play when I have at least 2 of my buddies on, so the ONLY way an Evelynn is going to stand a chance is if she focuses the lane that we're not in. I usually mid, with my buddies taking either the top or bottom... and we all shit on Eve, whether she is a "good" player or not, lol.
And BTW, you can't just play Eve like she never had cloak as she was made to be invisible and assassinating people. The only thing that makes her a good asset is her stun when she comes out of camo...
