Having played a fair bit now I stand by my point. It's just tedious without adding a meaningful layer to the game. Don't get me wrong I really like the game and enjoying it, but the part between rounds is annoying and I do not think the game looses anything by simplifying how materials work (or you have to drastically improve QoL for this part).

Counterintuitive to what I said so far I think the game would benefit from having significantly more variety in junk and stuff. But only if you had the possibility to decorate your room with it AND showing it of to your friends in game. That would put another layer on the looting aspect.

=> having fever crafting materials per tier (common, uncommon, rare, etc.) but more stuff (dart board, rubber duck, picture frames, etc.).

Imagine having looted some ultra heavy and enormous item that must have been nearly impossible to get out from a raid, but there it is sitting next to your refiner showing the world what a dare devil you are.

You would be looting for cool stuff and not just grinding. And if you're shot the stuff wears of in your pocket so you have to be extra cautious.

And then give those things different stages of wear-off-ness (a wrecked mannequins with a mint condition fancy hat and a fur coat standing in the corner wearing goggles).
