If you want to get a really good weapon in this game, it's worth playing with a gasoline canister, you can make a lot of interesting things out of it, from mines to guns.

You shouldn't try to force people to build what is essentially an overly complicated way of having a weapon. Traps, structures, and maybe vehicles sure, but firearms, mines and mortars? Ridiculous ask and something people would likely mod into the game just to avoid the tedium. Not to mention relying on bob the builder-esk tactics to solve for X would be an admission you don't plan to add anything to the game based on the principle of the matter I.E: Having working guns = we're expected to have events and horrors that may require us having one. Would be quite off-putting to people if we need to start fortnite building our way into dealing with events and horrors, especially as our only recourse.
