When I was farming them for acid gills, I found them anything but fun. Each room might as well be just one room. They are entirely the same. Generally cramped, so dodging gameplay is lost. And the challenge of being a maze is lost since you have a map, so it's never a question of finding your way from here to there and then feeling accomplished that you did so, but simply peering at the map and realizing that you missed a drop and have to backtrack now to get to that last container in the far corner. And then you have to find the door again...
Side note, I did finally start finding some other enchants in stash rooms with this version. Since the change that removed inner light, that is, but I never found anything but inner light before. I remain convinced that some sort of bug was preventing me from finding anything else. (Thus meaning the only way to get acid gills was to grind mazes... argh!)
