John Bierce's Mage Errant is another highly regarded ProgFantasy series - that has recently published its last book in the 'initial series'. I fully expect other works in the same setting though.

Personally I'm also a big fan of Sarah Lin's work in general specifically Street Cultivation and Weirkey Chronicles.

Tao Wong is another very prolific writer in this space - his non LitRPG series, and IMO his best work is the series A Thousand Li - which is a more traditional Chinese Cultivation setting - but without being a Translated Novel. Some ProgFantasy fans find the Progression in this slow.
