Ahsoka doesn’t have to die…

My friend was just telling me what could happen. If Ahsoka lives past order 66 (the one from palpatine ordering the killing of all jedi) Ahsoka could live on in the star wars eu! (expanded universe). She could have battles with Vader, which would be fun but a little sad :(. Should Ahsoka be kept alive? I mean, she’s not in any of the star wars movies! What do you think about putting her in an EU series?
