Can I get a source on the removal of birthsigns? I've been hearing it for months but no one ever gives a source and I don't remember hearing it or reading it anywhere official.
I don't believe there is one. One of the earliest references to the skills UI (possibly the Game Informer article, even) mentioned that Bethesda was
"preserving the player's ties to the birthsigns", which many people interpreted as saying that they were out and the constellations were supposed to be a throwback to them. Nothing has been said, that I know of at least, that outright says birthsigns have been removed. Todd never mentioned them when discussing character creation, though. :shrug:
