Choosing Dragonborn is a total scam?

I chose to be a dragonborn since i like reptiles, but now when looking at the racial bonuses this seems like a terrible decision. It seem ridiculously underpowered? Brief example comparison:

Dragonborn
Default bonuses: None.
Subrace bonus: Gain resistance to a single element (e.g Lightning, Poison, etc) depending on your chosen color, and a breath attack which can be used once and deals very little damage. Nothing else.

Human:
Become proficient in SIX weapons/Equipment,
Choose a proficiency in additional skill,
Significantly increased carry capacity.

Dwarf:
Default bonuses: Proficient with Four weapons. Gain Darkvision and resistance vs poison which is THE SAME as what green dragonborn get (except that the dwarves get this bonus in addition to other bonuses)
Subrace bonus (Duergar):
Empowered Darkvision.
Gains resistance against Illusions, Charm and Paralysis.
Gain access to two seemingly useful spells.

Surely this can't be real? :D
There must be some hidden benefit from being dragonborn that i am missing?
