The Frost map unfortunately was a bit more of a disappointing than I thought it would be. The "focus" point is in the middle, and the middle is not any bigger than any other map. Thus, shotguns are still useful, the areas between the spawn and the middle are almost of no use, and thus snipers are still useless, unless you decide to kill people that attempt to reach the middle, snipers gain some usability there. Besides that, due to the new shop system, I could always disable every nuisance weapon while playing specific maps (I.e. shotguns). But they can still be loaded from the kits. Making them unloadable will mean that for every weapon type once you load you would need to do a check to see if you have any of the disabled 30 weapon sets, doing ifvalues for item1 == HK: [y]. That's the way saving currently works, but there are not many values for that, there aren't that many weapons you can buy. If I am to do that for loading, it means including those on loading too, and also including everything else.
So yeah. No.
I could fix it up by adding more usable content at the areas that are currently spammed with trees, or make it so when specific maps hit, several weapon sets get automatically disabled. But that doesn't solve the kit problem. And I don't want to disable kits and have people run through the shops every time.
