That being said, Lux is one of my favorite champions, ESPECIALLY on Aram. Her poke is so amazing if you know how to properly play her, you can win mid lane most any time. Even against people like Kat who people always say is a hard counter to people without hard cc(silence, stun, etc for Kat ult). I find that unless the Kat is extremely skilled at what she is doing, she is more than easy enough to shut down with pokes from a distance. Kat needs to be a bit close to you to keep applying her damage, and Lux can deal all damage without ever stepping in the danger zone. Of course, if you get out of poisition she will most likely wreck your face--but honestly, even that is avoided by purchasing a Zhonyas due to its active.
