IIRC, male Miqo'te weren't playable in 1.0 because they were supposed to be exceedingly rare (in lore anyway, mechanically it was probably because lolzMithra) so it was only ever the females that went out to do adventuring and the like. So, adhering strictly to lore, yeah, monogamous relationships don't work.
In reality Miqo'te are the most populous race with catboys probably making up, at the very least, half of that overall percentage, so. At this point trying to justify or argue against anything Miqo'te do with "but it's the lore" is akin to bashing your head against a brick wall to get to the pie on the other side. Could it eventually work? In theory. But you're gonna have massive brain damage and head trauma before you ever get to that point.
