Dress up would be more of what they implemented into the game. If they added things that were for dress up and had little value ion combat or against the environment, then that would be the case.

Repair Skill
I'd like to see the repair skill more involved all around.
Like, you can break apart guns and gear and other items into various parts. And use those parts to make other things. Not here's the same gun, we can repair this one just like it.
Basically lets say the barrel on...
Ammo!
I would really like to see different ammo for guns. And if nothing else, some damn slug rounds for shotguns! Even if its rare.
I would love to see more creatively made guns (like the pipe gun and homemade guns). Also some more maintenance of the guns and melee weapons that are home...
