I'm with Guppy on the repair kits thing, They are an easy concept to learn since everything uses them, and the number of ingredients forces me to go out and scavenge for them... going through sleeper infested pois looking for the cloth I need.
Limiting repair to forged steel will suck until I can unlock it, which if it was like a17 level 40-50 or so. Traders often don't have it in stock, and I can recall visiting 3 different traders miles away on a minibike trying to find some to make something I needed in a17.
I would suggest keeping repair kits for most items, but just changing the gun recipes for repair to require those gun parts for the weapon. I like having to go hunt down ingredients found in specific locations. You already have a great incentive to go scavenge with repair kits, and I'd hate to see that incentive gone.
You to attract new players in the first 20 hours, but have SO much stuff they won't see til 30-40 hours in, or more..like the motorcycle, gyro, 4x4, electricity, and many weapon options.
Instead of unlocking them later game with points, maybe they need lower tier versions so new players can experience them earlier, and then unlock better versions with points later game?
As far as backpack dropping or item dropping while running, thats just stupid. If they are too stupid or lazy to make a chest and drop stuff before entering a sleeper infested poi, they deserve to loose it all, and will hopefully learn be loosing it.
IMHO hats part of the learn "to play better".
