Ah, the labs sound similar to a type of dungeons that were part of last season’s theme. I liked them too. There’s a new pit mode that is similar to greater rifts in Diablo 3 if you remember them. Not quite running through traps, but running through procedurally generated dungeons to reach and defeat a boss as quickly as possible. Those bosses started out with some cheap one-shot kills (now nerfed), but I find them pretty fun and prefer this mode of dungeon + boss to the regular boss rushing.
As Grim Dawn has been on my list, do you mind sharing why you couldn’t get into it? Anything I should know going in?
