Why do people ask for nerfs on a champion that was balanced for years?

The threads about her seem like they are posted by people who just learned that she has rocket jump + buster shot + high range. She's had those for SEVEN YEARS. (or 8 I lost track)
Given that she's been fine in most of those 7 years do you think she needs to be nerfed or do you think items need to be fixed?
Think people. Use your brains.

but anyways, it's not that she is OP but she is one of the best ADCs to abuse those 3 crit items + support items.
