Remember Braum? Originally his passive had the same symbol for all skins because of clarity concerns. It got changed because it turned out not be actually be an issue.
You're 100% correct here. The first time around because it was something that wasn't super iconic and we didn't want to cause more confusion with a new champion. We aren't against changing things, especially when we realize we're wrong and didn't make the correct call.
We made several changes to particles existing in the game, including Underworld Twisted Fate due to clarity concerns as well.
Another few examples here include PROJECT: Ekko's passive indicator, and PROJECT: Ashe's arrow. We didn't make the right design calls on these, admitted our mistakes, and had changes ready for the following patch.
We fuck up sometimes, to be blunt with you.
The projectile itself changes drastically. Personally I'd be far more worried about that causing clarity issues than the effect.
The original designs were huge offenders, and we changed the shape and the color of the particles to avoid them looking wicked similar to existing particles in the game. (As the game ages, and we have more and more skins, we'll of course have similar particles in some cases, and the Skins team relies on gameplay, champion, and playtest teams to help us make correct calls. After all, we're just here to make pretty things - they tend to pull us back a bit to avoid huge concerns.
Even with slight color changes, the pattern wouldn't have to change at all. It'd be pretty recognizable, moreso than many other champions and their skins.
The only other abilities that look anything like Lux Q's effect are Morg Q and Ryze W - which are the exact same effect, a root.
Morgana's (Q) is and Ryze's (W) were two of the biggest issues we had, particularly Dark Form Lux's (Q) binding reading as Morgana's (Q) binding . Morgana's (Q). While yes, both snares, it's still important to understand who they're coming from.
We need consistency across Lux's (Q), which was the biggest discussion we had. If you can't recognize that you've been hit by Lux's (Q) binding - which is the beginning of her full spell combo - you're going to have a bad time. Her passive procing off of it means a lot more than an AA done by Morgana after a (Q) binding hits.
In order to still keep with the thematic, you'll notice there are elemental pieces inside of the bindings - i.e. leaves in the nature form. While it may not be a different colored binding for each, we made a conscious decision to do what we could to include the thematic throughout the kit.
Calling this a clarity concern in a world where Project Ashe's and SG Jinx's ults exist in a fine state is kinda silly. You guys need to have a bit more confidence in your playerbase to not be incompetent.
I mentioned PROJECT: Ashe's arrow above, and I personally haven't received feedback regarding Star Guardian Jinx's ult, so I'd be happy to hear you out on this one.
It's not a matter of being confident in our playerbase, but keep in mind there are new players, and there absolutely an adjustment period for a lot of things. Hell, I've been playing since before season one, and I still need to adjust to some of the new skins that come out, and I'm the one working on them. There is a difference between adjusting to new particles and clarity, though. This is why some particle's don't change period, such as Jinx's Zap! indicator.
This skin already has an example of how to do this right: her ultimate. The ult symbol flashes a matching color to her element during the windup.
I absolutely agree with you here.
TL;DR Our primary goal is not not impact gameplay when making a skin. While something may look wicked cool, it may skew gameplay a bunch. Gameplay impacting animations, particles, etc. > aesthetics. As I've said, we aren't perfect and do make mistakes.
I'm happy to discuss this more, but keep in mind, I am on skins, so my primary expertise comes from skins, and the gameplay aspects I'm discussing here are based off of meetings we've had with several teams. :)
