He's kinda got a point though, since they arent really "copy paste" as some are saying, and they do have different internal structures and set pieces than other dungeons. Plus they are instanced, so this extra time could've been used to improve the structure or add additional graphic touches.

EDIT: They dont really need to make new enemies, just populate them with enemies that arent widely seen at those ranks. Now the boss enemy should be something large/fairly different looking than a normal enemy. Even if its a really big drake, it should have a different skin texture or extra additions to the model since they use that polygon shaving tech.
