I have one simple question for Larian. Why couldn't Astarion just... bite Cazador and become a true vampire? Just why?
Because when you're using bite accack, the target can't be an undead, duh!
Just kidding, I agree with the post above - this option is redundant because of the ascendant one. Also, Larian obviously wanted to make it a difficult choice: stay a spawn but be more or less decent person, or become this powerful thing, but sacrifice 7000 innocents. If Astarion had an option to just bite Cazador, there is no difficult choice. The design is a bit rushed in my opinion and I think this is why we have this logical problem here.
