Severely hope this is a troll post...
Don't move so obviously and you'll do better. Don't stand in range. E is harder to hit than it looks, Lux will primarily want to hit minions with it as well as the enemy, since it's her only decent farming ability, so if you stand off the minions you will have a better chance of dodging. The slow really sucks, E is primarily used for damage.
And as someone else mentioned, flash owns Lux. Any champ with inbuilt flash will have the advantage. Lux is also one of the squishiest champs in the game, if you can deal good damage and Lux overextends, you can probably kill her in a few seconds.
