Comparing dragonborn race traits with those of other classes is kind of depressing. They have zero synergies with any playstyle, no gameplay or story affecting traits, honestly their gameplay implementation feels like an afterthought.

For those who haven't checked, Dragonborn have 2 race perks, one is a dragonbreath spell that is so weak that it's literally completely useless after level 2. Like no hyperbole there is no situation in the majority of the entire game where one of the two Dragonborn perks is actually viable.

The second perk they have is some elemental resist depending on subrace.. Like really? Dragonborn were featured a lot in promotional materials, they're a popular pick for players, I don't understand why they were apparently given so little thought in this area.

The breath spell needs to be buffed at the very least, so playing a Dragonborn actually has 'some' gameplay implications and isn't entirely cosmetic at the cost of gameplay.
