That's neat work with the crests. It would be cool to put on different effects. A thought did just occur, though ... why do we have to even have the symbol by our names? Why not have the crest on like an armband like the Nazis (just an example, I'm not pro-Nazi or anything >.>) or on a tabard like, sadly to suggest, WoW? But of course, since it's FF do something creative? Maybe plaster the design on a helm, or a sword with it enraged on the handle or a guard shaped like the crest?
Also, the coat of arms deal with unlocking images depending on guild achievements to put on the crest ... would be cool to see
