Honestly my biggest hoarding issues are crafting mats, seeds, bait, and faded orchestrion rolls. Since I posted though, I've decided to get rid of all my seeds and bait minus versatile lures (thanks to the elezen in my comments), but I intend on keeping the faded rolls since I know I'm going to level alchemist soon (once I finish endwalker I plan on going back and leveling all crafters and gatherers). The same elezen also said that crafting everything is a bit bonkers and that I'm underestimating the undertaking, but mmos are supposed to be about the grind. All the mats I currently have are mats for the star level 50 crafts. I wasn't able to use them because my crafters didn't have high enough stats, which is why I put my crafters on pause. At least right now, if I never started crafting I wouldn't really have that much of an inventory issue. My issues with dye, materia, and other things stem from crafting mats taking up so much of my inventory. I can see how things change when you don't want to craft everything and are just speed leveling, or have already crafted everything and sit at endwalker with no or very few mats waiting for DT.
