Evelynn needs more counterplay.

Honestly, she doesn't have much. Allow me to explain. As a lvl 6 focused jungler, her pre-6 ganks seem to be the best of any lvl 6 junglers, e.g. wukong, nocturne, skarner, amumu, fiddlesticks, master yi, rengar, and more with her high-dmg and nearly garunteed cc pre 6. We'll start with her passive. She can't be revealed by wards post 6 which means that the opposing team has to spend large amounts of gold on control wards just to know if shes coming at which point, she or the laner can potentially kill and gain 105 gold advantage every control ward killed. Even if You do control ward and it isnt killed, she can just as easily lane gank. Not only that but being that red trinkets are of little use in the early/mid game for her, she can use a warding totem instead to provide extra vision to her team that most junglers wouldn't be able to. moreover when she is dropped to low health for whatever reason e.g. ganking or jungle camps, she can quickly return to acceptable health to gank again or clear more camps which again most junglers would have to return to base, meaning shes applying more pressure than normal. Moving on from this, her W is a dmg amp spell that can apply cc, bonus dmg, and even spell pen if she lands an ability. The cc itself is insane considering it forces you to walk away from safety, while in an almost garunteed 2v1 scenario making it significantly stronger than most. Normally I wouldn't really have a problem with this except how easily she lands it. With her q being castable 4 times, and 3 of those are tracking, that can make this incredibly easy to land. Her ultimate is insane. It's an instant aoe execute, un-targettability, and a dash all in one which means that if your avoiding her by playing safe on tower, she can tower dive easily with her high nuke dmg, cc, execute, and escape. Basically, her perma-camo combined with free out of combat sustain, mixed with her difficult to counter cc / dmg, + her instant aoe execute dash means theres not really many ways to play around her. Most evelynns dont even need high ap such as rabadons to nuke someone, because of how much dmg her kit has in it. Heres just one of many examples ; i was playing a game where i had hexdrinker, and barrier and was under tower. evelynn who wasnt fed easily killed me through my 2 shields under tower, without needing her ulti. INSANE. I'm not going to necessarily say that her dmg is op, there's many 1 combo champs out there. But its how much of her kit that doesn't have good counterplay in combination with her high dmg/cc that can make this champion obnoxious to deal with.
