Really? No unique dwarf traits in WoW Book?

The WoW book is really interesting and adds a lot of new and fresh ideas.  But the fact that they just say use the standard dwarf stats from the PHB for all the different dwarves is just insulting.  Especially when elves are given specific new features for each of the many elves represented in WoW.  I can kind of give a pass for Bronzebeard and Wildhammers, it's more of a cultural difference.  But, Dark Irons?  Seriously?  Additionally, where is our titan form type abilities and Dark Iron species specials from the WoW coming to DnD?  It's better to use Duergar from Mordekainens monsters of the multiverse than using this very insulting comment to use the standard PHB dwarf stats for a dark iron dwarf.  Very disappointed and certainly feel that the current designers don't give a damn about dwarves or their fans.
