To start off like Nedio said the Forsaken and Dalaran mages are a faction, not a race. A race would be Humans or Undead. At first glance, the first model doesn't look like an Undead but when you look more into it the model does. This could be a problem so I recommend changing it to be a bit more Undead looking while keeping the Human look. You could easily call it something like "Forsaken soldier, Forsaken footman or an undead warrior". For the Dalaran models, I recommend changing them into a more magey warrior type thing. Like perhaps give them a spell like an effect in the other hand and a bit of mage armour. If you take this approach ingame they could use both magic and mele abilitiesys you can even change their attacks to do this "if you didn't know". Another option could be like what Nedio said, a summoned golem or elemental. Personally, I prefer the more melee magic hybrid.
