When Robert Jordan made it public he had cancer, he also began the process of securing Brandon Sanderson to finish the series based on all his notes and how he wanted it to feel and flow from discussions with his wife. I was saddened and terrified as I was probably 8-9 books in at that point. When he passed and Sanderson co-authored the last 4-5 books, I was so relieved. It barely felt like Jordan hadn’t written them until the final 2 books.

I don’t think I want to go through that again lol. So, OP, I would count myself as NOT wanting to start a series left unfinished.
