About which idea from aydwan regarding Anakin you talking about?
I am always between keep anakin, his last shot - vader mask coming down and breath - and removing him completely as I like the thought of someone who doesn’t know who Vader is to get the surprise at the same time as Luke in the movie.
But then wonderful and chilling scenes like Ashoka vs Vader in rebels would be obsolete.
Basically that. In the version Ady planned on doing, you wouldn’t see Anakin become Vader.
