Sorry for necroing - but I have to agree, fighting Nere was a total disappointment (apart from the fact, that it was satisfying to kill the dbag) - he didn't really attack that much, most of the time, he just used a shield and ran away. I haven't done Grym yet - that will probably be my last encounter, everyone else, who isn't a deep gnome or deep rothé, is dead now or magically vanished.
I find navigating in Grymforge a tad bit vexing tbh.
I dunno, I think "obviously evil" enemy NPC's are kind of disappointing. I mean his voice alone is reason to kill him honestly.
My favorite villain was Letho from Witcher2/3 - I can understand his motivation and POV. He isn't a total monster.
