sry it took me 8 days to respond, i saw 'non traditional A/B/O dynamics' and got so hard i passed out :(

anyway!! i can certainly answer this as i love unconventional omegaverse dynamics! i didn't even like omegaverse 'til i found fics with those tags. i'd say non traditional A/B/O dynamics encompasses things like:
- alphas who like to get fucked by other alphas
- omegas topping
- uhh idk i read a fic once where tolkien takes omega hormones to become, like, omegaverse trans?
people rly go nuts with it and i love them for it

i would say "non traditional" is often what's going on when there's some commentary on gender roles and expectations, when there are rigid societal structures around the characters' omegaverse identities that they struggle against, and/or when people are fucking in some way that flouts the standard conventions whereby the omega is more demure and the alpha sticks his big pp in that drippy omega hole.

for all that i love reading non traditional omegaverse, what i've written so far has been a bit more traditional i suppose (i honestly just find omegaverse a bit hard to write as there literally weren't any omegaverse fics when i was last in fandom so i'm still not super used to it). there will be elements of non-traditional in the one i'm currently writing but mostly because all the relationships are so fucked up. this one by the cellmates writer is one of the fics that made me like omegaverse (vers stuff goin' on)

thanks for writing! i hope that clarified things somewhat :3 it's also pretty subjective what goes beyond the realm of "traditional" esp since omegaverse is not real (yet)
