Fair warning, Rothfuss hasn’t touched the Kingkiller Chronicles in a long time and there’s no indication if he will ever finish it. (My husband delights in taunting his mom by sending her articles about whatever project Rothfuss is currently working on that’s not the Kingkiller Chronicles)
You have a very similar taste in literature to me so I’d like to offer for your consideration:
The Expanse series by S.A. Corey (the show adaptation is also excellent)
Mistborn by Brandon Sanderson (first in a series but that’s the only one I’ve read so far)
