The game offers a large range of fights and dungeons in terms of both difficulty and overall complexity but I think some kind of extreme mode dungeons would be nice. I think there is still too large a jump in between a dungeon and say a Coil/Savage Alex raid and a middle ground there would be nice. Plus not everyone enjoys larger scale party stuff.

Doesn't have to be too much. I just don't like having the only decisions and choices we have to make in the dungeon being "Shall we pull one or two groups. Screw that lets get the whole room!"
