Summoners Rift Playing as any champ (specific instance - Vi). Others I have played with have experienced this as well.
When Lux uses her ultimate, the width of the beam is FAR wider than any of her other skins. I was hit at about 50-75% further from the center of the beam than I would have been hit if I had been hit with another Lux skin ultimate. I know that sounds like an exaggeration but it was a significantly wider beam than normal.
Riotmoonstones11 votesHey!
We're working on a clarity pass, based on some of the feedback we'd received. At the moment, her (Q) issues (the fade out) has been pushed to live. We are in the process of adjusting her (W), (E) and her (R), which, if all goes according to plan and is clean, you should see the changes in 7.1. All changes are currently on the PBE, but here's a quick breakdown -
Original Elementalist (R) v. her base (R):

Updated (R) v. her base (R):

(Q), (W), and (E) updates:
As a heads up, updates were done on all forms, but I didn't take 10 screen grabs/make 10 gifs. :P
Hopefully this clears things up! I checked the hitboxes of her base v. this skin, and they're the same. :)
Zepper1 votesThank you :D
Riotmoonstones4 votesOf course! Always glad to increase clarity and consistency! Since ultimate skins change so much, some clarity can be lost, due to us wanting to make something wicked cool. :P Luckily, you guys and gameplay reeled us back in. ^-^
Octavia5 votesBut your change doesn't seem to have done anything, the ults are identical except the beam at the end is jaggy instead of smooth. Doesn't make it any easier to see and happens after the ult, just looks worse.
Riotmoonstones1 votesPlayers noted that they couldn't "see" E. Lux ult until it was too late to react. We found a difference between the R indicator and the E. Lux indicator; when base Lux begins cast, the warning beam appears immediately -- with E. Lux, it started wider and quickly condensed into the warning beam. The R has been updated to display the warning beam immediately.
Octavia5 votesWhat's " E. Lux ult"?
The R has been updated to display the warning beam immediately.
So the animation is just sooner?
But why is the animation worse? Look at the jaggedness of the lines around the beam then look at the original

Old one has smooth curves, new one has jagged lines. AFTER the ult, the last piece of animation.

looks way worse
Riotmoonstones2 votesElementalist Lux's ultimate, her (R). Right, the warning. I'd replied to your last point in the other comment you'd made.
LostFr0st2 votesIt's WAY more clear now for me. Pass our thanks to the team.
Riotmoonstones1 votesCan do! :)
ImClaux1 votesI don't even have the skin and I hope they don't change the smoothness on those lines.
Riotmoonstones1 votesWe aren't - the image was taken before winter break, when changes were still being made.
Zepper1 votesE. Lux ult = Elemental Lux ult
CleverCactus1 votesWill lux R as a whole ever be update to be more clear? When she is on different height levels or gets displaced while ulting the visuals are not accurate representations of the hitbox.
Riotmoonstones1 votesI don't have a ton of context for this one, so I can't say one way or the either. I do know that there aren't any immediate plans.
edoxbox12 votesHi!
I'm from EUW-Italy.
I can't see difference from Original at Updated.
Is maybe for my dirt PC, but... :/ 
Sorry for my English.
Buona giornta ! :D

edoxbox11 votesUh! Thanks! :D Btw dat Ctrl+c\Ctrl+V XD
Riotmoonstones2 votesMwahaha. :3 You're welcome!
the Anarchit3cht1 votesyour use of "E." to abbreviate elementalist was very confusing.
eV Gumdrop1 votesHey KateyKhaos I really do enjoy you guys at riot communicating to members of the comminity and pushing updates that really help the game!
Riotmoonstones1 votesHeya! Thanks for the kind words! <3 We do what we can to hear out and act upon your feedback!
Octavia3 votesWhy does the new one have a jaggy beam after whereas the original as smooth? the cross lines after the ult, new one looks bad, the old one has smooth curves
surely that's a glitch?
also I can't even see the difference other than that
Riotmoonstones2 votesThe gifs were taken before winter break, and a gif isn't the best way to show off graphics. The beam's ribbons are still smooth.
Octavia7 votesBut I mean... it's nothing to do with it being a gif, it's plainly different
old http://i.imgur.com/dkaA57o.png
new http://i.imgur.com/e1WgbZ8.png
But if it's still like the old one when it goes live then... ok, but it's definitely changed in that image
Riotmoonstones1 votesThese were two different thoughts - gifs can skew what graphics look like (not in this instance but in general), but my comment also stated that the beam's ribbons were still smooth, as in, they're not broken on live.
Octavia1 voteswell as long as it doesn't change that's fine
dynamo3121 votesWhat is different? I can't find difference.

Sexy Jack Rabbit1 votesI'm a little confused Katey, if people couldn't see the E, why were the Q and W changed as well?
HR Cephei1 votesE. Lux = Elementalist Lux, not Lux' E
Sexy Jack Rabbit1 votesWell then if that's the case it still doesn't explain why the Q, W and E are seeing changes as well. (As linked by Katey)
Riotmoonstones1 votes(Q) Was changed because it wasn't lined up with the hitbox, and the (Q), (W) and (E) initial particle casts looked pretty similar, which meant a player many not be able to determine if a snare is coming their way, or if Lux is just shielding herself.
RavenHusky1 votesThanks for letting us know!
Riotmoonstones1 votesOf course. ^-^
HappySquid1 votesHeya! I dont see the difference between the E and W? they both look exactly the same! and as a lux main this is very confusing. I can see the Q and OMG i love the ult fix thank you so much <3 <3 <3 (hopefully those sneaky jagged lines in the gif dont go live!) but I'm really having a hard time seeing the difference. could you explain whats different between the old and new one?

The lines aren't in the game, I've just checked on PBE. For some reason it's just wrong in the gif.
HappySquid1 votesThanks! I still dont get the changes on the E and W, could you shed some light?
Crownguard1 votesThanks! I still dont get the changes on the E and W, could you shed some light?
I'm not 100% sure about the W change to be honest. The E change (in light form) basically changed the ball of light when flying from a blue-ey colour to more pinky-purple. I honestly think it was fine and this won't stop people complaining about it but we'll see.
Paril1 votesAre there any plans to actually add the rod in her W? It's weird having this be her only skin where there isn't a rod between the effect, and she literally says "wand away" but no wand! :(
Riotmoonstones1 votesNope, we don't have any plans to change that portion of the particles.
B0OM1 votesIs it just me, or does the base Lux model ult animation not sync with the particles? In the second gif you provided. The base model animation isn't synchronized with the ult particles - the animation completes before the ult actually does.
zombie1463 votesCan we get a video on the Q, W and E updates. I own the skin so I'm interested in the other changes aswell.
Sandrahy2 votesIt actually tends to hit less for me, even when they were almost dead center in the beam.
Dauthau1 votesIt actually tends to hit less for me, even when they were almost dead center in the beam.
Then maybe her ult is still just bugged in general. Not particularly biased in wider or narrower. She sniped me from their inner mid turret to the wall separating river from the purple bot-side jg. Maybe range has something to do with it?
Sandrahy1 votesI do also play on 130-140 ping (playing from EU to NA, don't ask)
But when people I am playing with even yells like: "how the fk did that miss, it hit you!"
yeah... that's when the salt kicks in. I can't really say 100% sure, but sometimes it just misses and sometimes I GUESS its a lucky shot because hitboxes.
Sexy Jack Rabbit1 votesOpposite to the Q, the end of the ultimate hitbox (As in, if they are too far away) is actually shorter then it demonstrates. This can make it look like it misses a lot.
Sandrahy1 votesI didn't mean the tip of the ult. I meant like
Sexy Jack Rabbit1 votesOh well no clue then, could be a visual bug or FPS lag.
Sandrahy1 votesWell, it couldn't be since my friend also questioned how it missed, several times.
I don't mind though, in my heart I hit 
Sexy Jack Rabbit2 votesI'm so confused! When you look at Gif shared on Twitter the Elementalist Lux Ultimate animation Lines are CLEARLY round and curved. But in these gifs they are very clearly jagged and sharp WHAT IS THIS TRUTH D:
