None of the robolegs should allow cargo on the hips, they should drain a bit of battery constantly.
Floating carriers should be disallowed on ziplines like they were originally.
Boots should receive random amounts of damage so that the player could be caught offguard, prompting him to carry extra pairs of boots in the future.
Battery drain should be increased flatly across the board for all items, extra batteries will become more important.
Lightweight versions of guns should cost more and have less ammo.
Phantom gas grenades should have an effect on Sam, requiring a gas mask for this tactic.
Ghost Mechs should have a wider detection range. It's too easy to walk around them, they are blind.
Mortars and rockets for vehicles need adjustments to their target acquisition speeds. Trucks go too fast for the weapons to target and fire in time.
NPC cargo from area recovery missions should emit strand visuals from an odradek scan, they are near invisible to players who deactivate markers in the options menu.
Every item should cost a lot of more materials. The resources are infinite, defeating the purpose of having a resource system.
It's a bit difficult to tell which direction armed survivalists and the like are facing. Their odradek's light isn't a sufficient tell when the enemy's silhouette is already glowing red and yellow from a scan.
The DHV Magellan must have an animation showing it dive into or rise out of the tar when a course is charted from the map. There already is a button to skip animations and jump straight into the ship so this would not be a problem. THIS IS VERY IMPORTANT
The BT spawning mechanic needs a complete rework. BT in gameplay and BT in story are completely dissonant.
Auto-aid request is a bad system, it is SPAM and players do not want to engage with these fake requests.
The Dowser needs to reveal her expansive boobs to the player.
Blood bags should not be in the item menu since they are already automatically equipped. They are clutter.
