The Lux Buffs
Lux is extremely hard to lane against because her poke and AA range are enormous. She seems to have to much range to actually gap close and does an overwhelming about of AOE in team fights. i am not saying she takes no skill. Everyone of here abilities is a skill shot, although her e is arguably the easiest skill to land in the game. I think the addition of the damage on q put her over just slightly over the edge in terms of AOE. I play in low gold and I seem to see her every game. I strongly believe that her R and E do plenty of damage and that she was already viable. I played her more than any other champion ins season 4 and I did just fine. Maybe just revert her back to her previous state before he buffs to q? She seems to have a huge win rate for the amount of games she is played. I am not sure how she fairs at higher or lower elos. I can only speak for myself but this is what I have encountered.
Also a tip to players, Yasuo's windwall does not block her ULT I learned that the hard way XD.
