Here's some feedback about things that I would absolutely love to see, that I think would make sense to add:

1: Looting skill tree. i.e Have a small chance to get an extra one of whatever you're looting. Maybe it's a 2% chance but there are ~5 abilities in the tree so it makes out at 10% chance or something. You could also have more inventory space in this one. Even if it's just 1 slot and there are like 3 or 4 of them. I think this would be cool. Coding passives isn't very difficult and Devs already know how to manage inventory space from the trader runs.

2: KEEP THE PVP. PvP is great. Literally nothing needs to change about it. I played exclusively solo and if I played smart I could wipe other teams. Ai is more of a challenge solo but you also get all the loot if you kill them. The game greatly incentivises you to kill AI, and I feel like the people that say they don't like the PvP just did this out in the open while missing half their shots, causing them to get 3rd partied by another, more cautious/quiet team. If there's no PvP or "restricted" PvP, then the game will die off faster than concord. The emote wheel is also fantastic. I was able to make friends with multiple teams just by using that.

3: DO NOT CHANGE THE GUNS. The guns all feel perfect. They are fucking perfect. Most people used the stitcher because it isn't semi-auto and it is tier 1. Most people probably didn't even get to tier 2 weapons, let alone be able to craft them. The SMGs are good. The shotguns are good. The ARs and DMRs are all good. The TTK is perfect. Not too fast, not too slow, with ALL of the weapons. Please don't repeat THE FINALS' mistakes and slowly nerf everything into the ground just because the large majority of a subreddit has absolutely no idea what they're talking about.

4: AI is all good. There's a specific way to kill each one and the difficulties of them all vary. I'm sure people will complain about certain enemies, but I think that you absolutely should feel terrified when a drone is shooting rockets at you or a behemouth starts leaping towards you while making loud noises.

5: UI and everything surrounding it is all very good and very easy to understand. Even for new players. Item descriptions are also good.

6: The addition of being able to switch the camera perspective, while also switching what hand you're holding the gun in, is the single best feature I have ever witnessed a game doing. This will become a new standard and you will be the masterminds behind it.
