What's the deal with animated avatars?

[Vader]

Which one? That only Fellows and up can have them, or not having them at all?

The one that i wrote |-/ ........ If you look closely you will see that i only responded to your first point.

Whats the point in fellows etc only being allowed to have them, none at all that i can see. It's either all or nothing, but as they are crap anyway theres no point at all.
