I can tell you that 'normalized' means nerf. When balance teams start throwing around 'normalized', 'reallocated', 'redistributed', etc they're just nicer ways of saying nerf(in most cases).
"She isn't getting nerfed, she's having her power reallocated. Believe us, she's going to do tons of damage still."
"We are going to be normalizing shield power. Karma isn't necessarily getting nerfed, because all shields are being streamlined simultaneously. That means she could potentially be even stronger after this normalization!"
See how much nicer that sounds? Diana, Zac, and Kindred aren't bad in Solo Queue, they've just been normalized down to a healthy state.
