Recently SE decided to force everyone to have a forum avatar based on the character linked to their account. Considering the limited amount of forum avatars, this somewhat caps the variety of avatars on the forums.

I suggest that to add a little bit of variety, forum avatars have an option to be shown wearing one of the artifact sets, but only if the account linked to the picture has done something.

For this it can either be that the job level is above a certain level, or perhaps that the character has the job emote for that job.
