I suppose it makes sense for it to be tough considering that it's intended as an endgame expansion and it's also replicating the new character low level experience with the scadu blessing system

I have actually found that the Land of Shadow has heaps of alternate routes to places, they're just much less obvious than before. The map is so wildly vertical and overlapping that finding a spiritspring or a tunnel or one of those cliffside staircases of protruding gravestones can take you to a whole new area
