On the MYMU, can riot do something about LB?

I doubt her 45-46% consistent win-rate is enough to warrant another nerf. But you can try making a circle-jerk about it.

Is fine the way she is.

You must have not played before she lost the silence.

T'is how LeBlanc is supposed to be. If you can survive the laning phase and not let her get kills, she'll fall off really bad during the mid to late game. But give her an inch, and she'll take a mile
