Why would Manqo'tes not be nearly as bad as Viera? It's already been revealed that they wrote that Lore BECAUSE they'd already decided on Female Viera to be the counterpart of Male Hrothgar. There was not 1 Male Miqo'te in 1.0 (Nor Female Roes until they made Merlwyb, and she was made as part of the storyline to set up 2.0) and in 2.x+ there's maybe 4. Koji's already said that the Lore gets bent all the time when the MSQ team gets an idea, or they want to introduce something like BLU, or for side story quests, and it's the Lore team's job to see how they can bend it to excuse that.

There is literally nothing stopping them from saying "Well, the Dramaturge was only talking about the Viera in the Rak'Tika Greatwood, the Male Viera in THIS area do venture forth every once in a while." (And given that we're going dimension-hopping now, there's no one to say that they have the same rules in the First, just look at the Dwarves=Lalafell thing)

You're ignoring what other people say to repeat your own talking points.
