Some ideas for small buffs and QoL changes for Lux.
is a champion that's pretty fine in balance for the most part. But, some small adjustments could really benefit her.
Take her W, Prismatic Barrier. It's a damn strong shield, AOE, and a potential 180 + 35% AP Ratio twice is massive. But, it has a significant cast time. Despite it's strength, the fact that Lux has to stop to cast it means it's not worth to use sometimes because doing so gives her pursuer enough time to catch up.
Also take her E, Lucent Singularity. This is the AOE Sphere she tosses out that slows if you're not familiar with Lux. It's mana cost, as many Lux players have brought up again and again, is too high. It's 70/85/100/115/130 at ranks 1-5. I understand Lux is not supposed to be able to recklessly spam her spells like a mage such as Ziggs because she offers other advantages like significantly more utility, but having a normal ability cost 30 more mana than an ultimate is a bit much, no? Can we consider lowering it to 60/70/80/90/100? I'm sure it wouldn't make her broken.
This last one might be a bit much... but it's something I've just personally noticed playing Lux- her pushing power is weak. Unless you're doing REALLY well, her E will not be enough to clear a wave. So, you have to auto the rest, which takes up a lot of time. Seriously, even if lanes where I'm more or less winning against my opponent, a lot of other mids can just shove Lux to her tower and she can't keep up with pushing unless she burns her ult, and even then, that'd only help with 1-2 waves. It's a weakness Lux doesn't really need.
So, I've been thinking. Allow Lux's E to deal additional damage to minions as it "powers up" on the field. (I mean that her E visual looks like it charges up, but letting it remain before popping it doesn't do anything). Let's say, 240 + 60% AP to 280+70% AP at the end of the seconds Lux can delay popping her E.
