Breath attack is pretty bad even in tabletop, but at least there the Dragonborn have other racial attributes to warrant picking them over something else.
What's comical to me is that even with mods that over-tune breath attack, its still not a better choice for your action than a weapon attack or spell just because of how damage scales and how the action economy works. The only situation where using breath attack is the best use of your action, is if your only other option is doing nothing at all.
