I decided to buy Evelynn today, knowing that she was "bad", and was surprised with how fun she is. A lot of people say she's terrible, and even had a few people call her "trash" while in champion selection, but I ended most games with a positive, fairly marginal score. So that makes me wonder, is she really that bad?
Edit: To make things a bit more clear, what exactly is the reason why everyone thinks she isn't that good?
