Honestly the only two progression fantasy series that I can recommend are Cradle by Will Wight, and The Immortal Great Souls by Phil Tucker.

Warformed: Stormweaver is also great, but only the first book, Iron Prince, is out.

I'm currently halfway through The Last Echo of the Lord of Bells by John Bierce, as well as procrastinating starting Waybound by Will Wight. Progression Fantasy is my thing right now.

I'm here to fight the good fight. Huge Sanderson fan. Really wish we could get the progression fantasy subs here too, but that's a pipe dream at the moment.
