I'm almost certainly an outlier here, but I'm also a fan of the "no fault" mc story. In part because a lot of my favorite mc effects involve people being pushed into extreme arousal (I personally trace this back to watching the movie Dr Alien at an impressionable age). This leaves the door open for stories like "oh dear, the clumsy scientist knocked over the experimental chemical, and it's having an effect on all of us!" and "ever since that fertility idol arrived in the museum's collection people have been acting...different".
I certainly enjoy stories where there is a dominant/controller as well, and voted for my favorite combinations in the poll. Just felt the need to give a voice to the "Oops, all subs!" fans out there.
Definitely a plus.
