Actually, they have shown several female Time Lords ever since way back. All inhabitants of Gallifrey are Time Lords, and there are women in Gallifrey, which means they are female Time Lords. Also Jenny, the Doctor's daughter is part time lord, Missy, the last incarnation of The Master is also a lady Time Lord(she was revealed way before Hell Bent. They didn't show her regeneration but it was obvious enough as she is The Master who was previously male). more here: http://doctorwho.answers.wikia.com/wiki/Are_there_any_female_Time_Lords |
I think you've misread my comment. I didn't say there weren't any female timelords (in-fact i started off by noting we have no idea what the gender split is; we know there are some male and some female, but not the ratio), i was talking about the prevalence of gender switching. To the best of my knowledge 2011 is the first time it was ever brought up, and Hell Bent the first time is was actually shown on-screen. I brought the latter up because it allowed us to see the reaction of another timelord there, which was relevant to what i was saying (that the show has in recent years presented gender switching as a thing that does happen, but isn't the standard).
