Lol everything except the lobby and casino is an istanced dungeon on PSO2, c'mon guys please! Cocoons and towers are indeed a dungeon too, but they are very simple, I mean VERY simple, all of them with the same blue VR space-like look, too shorts, with no loot inside and at least for now no mechanics and/or little puzzles to solve or switches to unlock new areas with, which were all things that were in Pso1 and Pso2 and in the other entries of the serie too. A jungle, a volcanic cave, a procedural generated maze which isn't just a blue room with one or two enemies. Something like that... I thought it was pretty obvious.
That's exactly what I think, hope sega drop that coccoon VR boring space and make more unique instance.
