Indeed. "There have always been female Custodes".

The now legendary statement from GW. Goes to demonstrate how important "established lore" is to the owners of the thing. Rumor is they were forced into a corner by Amazon due the now probably canned show.

So you just kinda invalidated this whole rant with this part. You've never played a female character unless it was the only option. So if they make it the only option, you can play it just fine. Problem solved.
