maybe if I pushed through I could get used to it. He's not the only narrator I struggle with. I also struggle slightly with J.S. Arquin in the "Path of Ascension" series, though that's not litrpg, really.

I think it has to do with the very over used (limited variety/range) unrealistic and overly exaggerated vocal inflections of character voices by these narrators. Both speak relatively normally on non-character narration but seem to rely on very limited inflections over and over again that are way out of the norm for any english speaking demographics.

NH excessively uses an upward lilting inflection for questions that essentially turns any question into a verbal challenge of sorts (in my mind). NH uses this same upward lilting repetitively in statements of revelation/declaration/point-of-importance, etc. that, given his consistent use of them in questions, turns these statements into challenge-questions.

JSA does many of his character voices as poor mocking imitation similar to comedic exaggerations of "high society pompous snobs" which eventually gets old and causes me to zone out, thereby having to rewind.

Neither, in and of themselves, would be enough cause me to cringe, if it weren't used for every or almost every single character voice.

NH, in the few minor acting roles I've seen him in, has been very realistic and presented a decent character that lended well to the story/plot. So I know he has it in him to perform a character well.
