With luck they'll actually listen to the valid feedback that this race doesn't resemble the WoW art style at all and give it the revamps it needs. Doesn't need to be beefy, just needs to look more like any of the WoW dragons do.
Will likely never happen for Death Knights because passive rune regen is locked behind both Mind Freeze and Icebound Fortitude. The Spec trees look solid for DKs but the class tree needs major work.
Rune regeneration shouldn't be locked behind Mind Freeze because you don't always need Mind Freeze for all content (ie: some raid bosses) but you always need Runic Empowerment or Corruption.
