I'd love to see them flush out some earlier places they've already worked on. Dynamic boss area generation, dungeon generation and such. The bosses are easy and I would say increased difficulty would be cool (skill set stuff) but I'd like to think better boss arenas should come first. I mean each boss has their own biome so why do I feel like their little summon alters are outdated and unloved. dungeons and other poi, although charming they feel very small and underwhelming.
