When you aren't registered with a multiplayer coat-of-arms, or you're offline, coat-of-arms in the build menu ficker very fast between different images. It's pretty annoying. Instead, I think they should display a random one, like opponents do in the "combat" option.

Oh, I never saw that. Yeah that would be cool, especcially if you want a challenge and you want to do a random CoA's. That's funny.
