Animated signatures will be like unskippable ad. It's gonna be so much annoying. Have you ever visited some website with a lot of banner ads? You can only see some content around those ads, and most of the webpage is filled with them. I don't wanna be a part of that. Instead of making it animated, why not just select some dedicated colors only available for legendary members? Red, green, blue.....something like that. And signature should be made using those colors only dedicated to legendary members. Design could be the same but color code could make them unique. Just a thought tho!
