I guess you couldn't see if dragonborn follow Fizban rules like being able to use their breath weapon as part of a multiattack if they have one. Or it being useable proficency bonus times a day/between rests.
Sorry, I didn't try a dragonborn. Blackheifer posted here a link to a vid of someone who it looks like some time playing a Dark Urge dragonborn that might give some more clues as to how they'll work. I'm not watching that one, though, so I can't be sure. There's no way I can avoid spoilers entirely moderating here, but I'm trying to avoid as much story stuff from beyond the EA cutoff as I can!
