Why are roleswap AUs pretty much the most common types of AUs?

That and genderswap AUs.

Never seen a roleswap AU before beside the GF one

There's a WOY one, and I think an SU one

sorry you have shit taste

Because "AUs" are just "What-Ifs", and switching roles and genders are going t9 be the first thing most people wonder about, off handedly

I thought modern AUs were most common. They are trash of course.

Because they're the easiest ones to envision and imagine.

How so?

>>91236761
Any examples?

Because if you have good characters then altering the dynamic in which they interact is a very easy way to see their personalities and decision making skills in a new light

This AU has potential. I like it.

>>91238338
Neat.

I guess so

Probably for the same reasons that costume swaps and "this character in that pose" are the most common filled requests on drawthreads. It doesn't require any additional research for either the creator or the viewer. It's immediately understood.
