Do you guys have any recommendations for mods which seriously improve aspects of the game in ways that you feel are necessary, after installing them? Like, I just got into modding and added the mod which balances bug enemy audio so you can actually hear heavies, and now I can never go back.

Any other core "feature" mods like that you'd recommend? I'm not really interested in silly mods, like the ones that add music to extraction or replace models with meme versions.
