Since I don't have a PBE account, this is the only place I can go to complain where Riot might see it (unlikely).
What's the deal with the Lux changes? This isn't balancing anything, I see no balance in a 15 second ult (with a stacking cool-down on multiple kills) at max cdr and level.
Lux does not need this, she's in a great spot as is. Isn't over-played, isn't under-played, can still hold her lane while simultaneously having weaknesses to exploit.
A 500 base damage and 75% ap scaling ULTIMATE ability does not need this.
