I agree with that, though perhaps not as strongly as you.this tendency of epic fantasists to switch characters is tremendously annoying and overused.
Though I am enjoying Abrahams's King's Blood at the moment, I think it would really annoy you: the characters are every 10 pages or so!
Happens in SF too. It's a modern style thing.
There are times when I much prefer the old-school linear narrative: might be what keeps me reading the old stuff!
