Femslashers I hung out with in Merlin but found back seem to have mostly split between Teen Wolf - plenty of highly slashable girls and women! - and Avengers (badasserie all around). My limited fannish experience of femslash shippers has us often more of less follow the same big waves as the rest of their fandom, as much as the canon allows. (However, my fannish experience is fairly limited, and I hang in pretty short-numbered troupes of merry multishippers who wish for more femslash and poly and multi in everything.) So when my show died, I went out to look for something that had agreeable basic dynamics that would enable me to easily find back what I wanted - for me that's places that had a diverse & interacting cast that would also for team!fanworks, multishipping, and ladies.
