She is very good in the right hands. The reason most people don't like her is because she isn't spam happy like say sona, and she doesn't have the tankiness of taric, thresh, blitz, leona. But if you use her with a good ADC (long range aa poke [cait, ez q, ashe] for e) and you know WHEN to land your Q, and how to fully maximize your W (knowing whether or not to have it double cast allies or enemies), you can be a god support. However, if you go in with the mindset of a keyboard rolling support, you are going to fail hard.
