First off. I've absolutely loved playing illuvium overworld for the past two weeks! can't believe how much fun I have been having. I'm a big Pkmn fan and enjoyed Palworld earlier this year and think this can be another pulp culture hint to the genre.
With that being said I found that with upgrading my drone equiment in particular the Harmonic upgrade line is too easy. Tbh I've never encourage a buff to a crafting game before as I personally hate the grind but in this case and given the illuvium economies with its other games I feel as though the crafting chain for drone upgrades needs to be 10x the material requirements for the region 3 mats and at least 50-100x on region 2.
I would also say that the advanced and supreme upgrades could also include the R0-R1 region mats like Neodar ingot as well to give the game more longevity and add value to the ore mats from these regions. For the amount of hours I've played over the past two weeks (which is a lot less than top players and professional extractors can play) I am nearly done with my second Supreme Harmonic stabiliser and it feels like that was too easy and quick to do. With the mainnet launch around the corner I think this needs to be buff to give these items more value and meaning in achievement.
I think this would be beneficial to do before mainnet as material cost requirements can easily be reduced but increasing them post launch could not undo economic damage and making a nerf post launch if you had too would be a positive to the new players that join rather than having to buff the requirements later on.
