Really? What is with all the Cathy hate? I would have expected her to be number one, or perhaps number two after Octavia for those that like older women, or FemDom, as you said. So far, second to Octavia, who so far doesn't really grab me, but give it time, Cathy is by far the most interesting character, as a person. Daisy and Riley, so far, have zero personality, and are there just to give the MC some side action while the main story proceeds.
Even Liu has way more personality so far, but I agree, that so many players want all the women characters to be "pure as the virgin snow", that I am not surprised that she is low in the rankings. I like how Liu's personality is just starting to show, but her face has always looked a little odd to me. I am not sure why,
