Not all Miqo'te are despicted that way, though. There's a number of Miqo'te soliders in the Maelstorm who hand out quests. The commander of that Company is in fact a female Miqo'te. There's also the U tribe in the Sagolii Desert, where most females are huntresses. In the Black Shroud, you have the Coeurlclaw Poachers, who are mostly females too. Though in those two last cases we have the Unfortunate Implication of them being patriarchal societies: in the U tribe, the only position of power seems to be the Nunh (which kind of goes a bit against lore, ironically) and the other two males act as 'wise men' and sub-leaders. In the case of the Poachers, you get a FATE where a male names himself "King" and you have to slay him. Which, again, is a bit odd because the lore we had stablished Moon Keepers as being matriarchal.
We could argue that in those case there's the justification that tribal Miqo'te society is probably much less advanced and modern that those of the city-states, so I guess nobody would be surprised.
The problem with Miqo'te concubines seems to be mostly a problem in the Ul'dahn regions and Costa del Sol, where the mentioned FATE takes place. Though if you look around the town and in far to the north, you'll see there are some Roegadyn females around, too. Of course, they are outnumbered by Hyur and Miqo'te females.
All things considered, I'd say it's a stupid case of fanservice.
