I'm also into the whole dark romance thing and I loved what they did with Astarion, so much that I couldn't get myself to romance anyone else in the game but with this new patch, as I've expressed so many times, I almost can't stand to look at him anymore, I hate his character.
I had the same reaction. It's not just AAstarion, but in general I can't watch videos with Astarion anymore, even the ones where he's spawn. At the moment I've also stopped playing it: I play it from time to time with a friend, but I can't do it alone...
