This is actually possible to achieve, but o think they create less priority to it because of the signature space which a hero and a legendary rank members have the same, that makes it look more or less thesame, you can see that other lower ranks like sr member and full member have a different signature space, but now left for the campaigns to either make a little difference in their signature codes to differentiate a hero member from legendary, such can be in form of additional colours lines or designs made or leave it as it has always been.
If you read several posts in this thread, less than 20 because it has only 1 page so far, you would know some facts- Animated avatars were allowed but disabled years ago. Because forum members saw animated avatars are annoying and the core admin (theymos) had the same opinion. He stepped in and code to detect all animated images for avatars and reject such images when people try to upload for their avatars. Only grandfather members still have animated avatars today. But if they take their avatars off, and upload same images again, forum will reject it.
- Animated signatures would be more annoying than avatars so no chance to see allowance for it.
If you are curious, this one is for you.
Avatar space is not negotiable as I lose my animated avatar if I remove it.
