Hero-Legendary rank member signatures tend to be same as far as most as most sign campaigns go. If animated signatures were to be possible, it should be available for legendary members to make the distinction between the two ranks. I'm interested in creativity signature creators will bring in as well.
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.
