Not that I'm not excited about a Project Lucian....but...
...Why give him two skins with orange particles?
This would deter a few people from buying the skin if they already own Hired Gun and are ineligible for a refund for it.
The same thing happened with High Noon Yasuo. I myself own both of his skins because I love him, and I DO switch between them, but it's hard not to feel like there isn't much difference between the two skins aside from the model and the voice.
You COULD solve the problem by making Lucian's particles a bit more yellow and red. His particles do naturally feature a combination of blue and white so it would still look good.
