Could Lux use a revamp?

Lux is like a turret at near death; high damage is done in short bursts, has long range, is not very mobile, and dies quickly if there aren't minion/champ support.

I don't understand why champs like Lux haven't been touched, especially lately with the new meta being fast marksmen/assassin champs with high dps. Lux is the type of champ who, on her own, is not hard to play. Her E is almost always a guaranteed hit and her q is a sightly above average skillshot in terms of difficulty vs damage. Her w is really a placeholder spell because they couldn't add another combat spell, so I won't touch on that.

The problem with Lux is that you could be doing not much wrong and still die simply because you play Lux. I was playing a 3v3 on TT and the opposition LeBlanc would ignore the tower I was standing under, teleport past my q then burst me down with about 700 damage with >400 ap. She would then escape with her teleport. I had about 30 more hp than her, was standing under a turret, and died in half a second.

Sure, LeBlanc isn't an easy champ. The point isn't that, however. The thing about Lux is that they made her squishy to counteract her ap ability. The thing is, she is not a strong mage anymore with a number of mages with comparable cc, better ap scaling, better sustain, and in some cases higher burst damage. She is squishy, isn't fast, and has pretty high CD all to make her balanced but her ap just doesn't cut it, especially against champs with dashes or teleports because that literally circumvents Lux's arsenal. She's basically become predictable and one dimensional, and most champs have a pretty easy way to avoid taking lots of damage from her.

I personally would just give her extra base MR and armor (she's supposed to be a highly touted mage - surely she has more MR than a tree?) and be done with it. If she can just be killed at will, there's not much point in playing her, is there?
