I loved the first season because of Taissa but since she hasn't been on it it's really gone downhill. Her leaving is definitely not the only reason but I do miss the first season, but I am somewhat keeping up with AHS because I want to find out how all the seasons link.
She has a pretty big role in Coven (third season) if you haven't watched that one yet!!
I'm also really intrigued how they all link up - the only connection was how Pepper ended up in the asylum after being in the freakshow but aside from that i'm totally lost (not great at figuring anything out or inferring i usually need it stated point blank)
