I wish the linkshell crests more closely resembled a coat of arms and less like something my brother could come up with in MS Paint in under 5 minutes.

Preferably, all linkshells start with the same, rudimentary list of art to place on their crest. But as the LS progresses through the game, and start getting achievements under their belt, the list of art for the crest explodes. Killed a certain NM during a raid, put it on your crest. Won over 100 airship battles and are now the terror of the skies, add that to your crest as well.

Something that is dynamic, fluid and grows with your character and LS. Not something where you are stuck with the gaudy colors and plain pattern that the LS leader picked almost a year ago.
