Fair. Counterpoint: depicting the 'Rand has a harem' element of the books was always going to be problematic. The cleanest way of keeping the arc intact was to reimagine Rand/Avi/Elayne as a polyamorous arrangement and remove any romance with Min.
This way, everyone gets to keep basically the same relationships (only adding a romantic component to the already deep Avi/Elayne relationship) while side-stepping the harem problem. Min can retain her place as Rand's advisor (a seed they planted back in S1), so the only thing that is lost are the romantic feelings Rand has for Min.
The only place I could see this being a problem is
But (a) you don't need a romance between Rand and Min to make that work; and (b) it doesn't have to be Min.
All in all, I think it was a pretty obvious and elegant solution.
