YES! See? We all agree on that.
A valid question. There's various reasons why I want Dorma back.
She's a strong character who gave Namor, and everyone else around her, a difficult time. I mean, look at the wringer she put Krang through! I love Namor and Emma together, because they both can be so snarky. Dorma was somewhat similar, but more ... lethal.
And she has the added advantage of NOT being unobtainable. Unlike Emma or Sue, Namor wouldn't be a victim of romantic triangle plot device.
I don't necessarily want Namor and Dorma to immediately return to their old status quo, i.e. married. In fact, I would love to see her be a giant monkey wrench in Namor's love life / political marriage. That's a story I'd like to see Marvel address. Atlantis needs a queen, and an heir. It's long past time for Namor to address that, whether he marries for love or not.
I don't think it takes away from Namor's character by resurrecting Dorma. The writers already sort of did that, or more precisely, Byrne did that, by having Namor move on and marry Marrina.
