I liked everything in the DLC except for the Cubes and the final boss. The difficulty is frustrating because it demands high precision, multi-tasking, and dodging to a level that sucks out the fun. Regular combat arenas are much more enjoyable and are packed very well here. It feels like the frustrating parts were intended that way to give a sense of accomplishment, but rather I was just happy to move on from those sections and never touch them again. If the final boss did not have checkpoints I would have rage quit multiple times, so I give them credit for that.
