[@Mordon]Tbh I've only ever beaten the game with Dwarves in Origins because I am a huge Dwarf fan on almost any fantasy series. But I admit I was thinking of the initial cutscene about the history in Origins, so you're right. I'm thinking though that the Dwarves still fought a fair bit behind the scenes though, while the Warden fought above. But I can still edit it that he fought mainly as the Blight ended.  
[@Saephod] Yep, intentional :]
