I'm often looking at the ground and don't really register from my peripheral vision which way the dragons are flying (which is I assume how you tell whose Breath is whose?) It's also pretty common for multiple players to play Breath in the same area at around the same time. It would be nice to have a way to immediately identify the owner of the Breath.
It would also be nice if the animation matched the damage but that seems like wishful thinking until 2.0 based on how long it's been broken.
