[2020] Nemesis cyber bullying with the bird

I think something was lost in translation between the original internal context and the patch notes. The context was meant to say that we began looking at Anivia because she felt very underwhelming even when technically balanced. Then, she lost a lot of power in preseason midway through that work, so the resulting changes were shifted to be more power-positive than the original plan. I can see how that did not come through in the final wording, sorry about that.
