I only really like canon divergent AUs that explore what would happen if the plot was different. So, something like what if Ben Solo had never turned into Kylo Ren or what would've happened if Finn and Poe found each other on Jakku after the crash or what if Rey's family came back for her.

I'm actually really pleased that TFA fandom wasn't immediately overrun with modern AUs or high school/college AUs. I have a few fandoms where those seem to the only types of fics written and I avoid them like the plague.

I enjoy a good AU occasionally, but after awhile I find that they all start to sound the same. That or the characters' personalities are changed so much just so they fit into a specific coffeeshop/high school/modern day AU plot and it feels more like original fic than fan fic.
