I think Maiev has shown some love to her kid brother, and that might be one of her weak spots. That is some characterization that almost softens her. He helps buttress and contrast her.
Not to say her characterization is tied to men ( Illidan, Jarod, her shando in wc3). There may be a bit of bitterness in her that she was passed over for Tyrande.
Angry Police Woman might be the most fun part about her, but I think Blizzard has given her some motivations and characterization.
Aggra…. not so much. She is a newer character, and she is already lame when compared to Garona or Geyarah or Draka or Zaela. It certainly isn’t that the Orcs lack interesting female characters. Aggra barely stacks up in that sort of pantheon, and she would have a hard time even trying.
I don’t rule her out for future progression, but at the moment, she is pretty much just some broad saddled to Thrall to make dad jokes and jokes about his wife being his better half.
