If the Lux buffs on the PBE go through she's going to become FotM and get nerfed
unless Riot does the same thing they did with Gragas Q and reduce the range to compensate.
Short of that however it's sad how easy it is to see her pick/ban in soloqueue if these changes go through and get nerfed into a state worse than she was before the buffs.
I'm not a Lux main, but if I was I'd be dreading these buffs because there's no mistaking she will break mid lane in lower elo and get nerfed for it.
For those of you who haven't seen the changes yet: http://www.surrenderat20.net/2015/06/611-pbe-update.html
Will bump in the patch after the buffs go through once her nerfs get revealed.
Edit: I feel like people don't seem to understand that I'm saying Lux is going to be oppressive in lower levels of play, not OP. Due to her skill floor being lowered she's going to crush casuals by people playing the champ for the first time in mid lane.
