Why are there so many Evelynn haters?

Evelynn may not be very viable lategame, but if you really think about it, she is the perfect early game ganker. Her abilty to stun, be invisible, lower armor/mr, and do steady DPS due to her hate spike is the perfect combination of spells for an early game ganker. Let's face the facts, people are always out of position, Eve, Shaco, and Twitch are some of the only people who can tank complete advantage of this without the person seeing it coming. Eve seems viable to me. SorakaBot of EU server, just recently got to the #1 slot in Solo Ranked, with his most played hero being Eveylnn. Next time you see an Evelynn, don't laugh, be afraid, and be careful.
