I've been griping to Gazz for weeks now to increase early game firearm damage and nerf zombie kill xp 30%, and double passive XP gains, at least roughly. I'd do it but I'm busy overhauling the entire economy right now because by the time you can afford a gun or something cool you can craft your own better one and most prices are just all over the place making traders pretty much worthless. I'm going to stock them with building supplies, more ammo, more meds, more food, etc. Its not going to be a one stop shop for everything you need, but they aren't going to be worthless any more.
