Think the reduction in Gjall spawn was all that was needed. It did start to feel a bit excessive and less "oh ♥♥♥♥!" when they spawned after every hill you crest.

The rest of the nerfs were too much imo. The Mistlands are the last area that exists currently in the game. I want them to be brutal on arrival and hard once fully geared. Instead they're maybe hard on arrival and trivial with gear now.
